Whakaahua 3. MAX456EQH MAX456EQH MAXIM MAX456EQH MAXIM 06 In Stock: 8005 pcs Te Whakaata Whakarārangi Kaha

Pūtake: Ngā Āhuatanga Rorohiko / Maxim Integrated, Rārangi Raraunga MAX456, Rev. 2. [1]

Kei roto i te taputapu he rārangi e 8 × 8 me te 64 T-switches e whai ana e waru ngā tārua putanga kānāka. Ka taea te hono tetahi input ki tetahi, ki ngā putanga katoa rānei. Ka taea te whakatakoto i ngā tārua ki te āhuatanga teitei-pātea, ā, ko te input LOAD e whakahaere ana i ngā rihita roroho aktif i roto. [1]

Ka whakahua te SER/PAR i te ahua whakahaere matihiko. I te tauira pātea, ka whiriwhiria e A2–A0 te putanga kotahi, ā, ka pānuitia e D3–D0 te hono whakauru, te whakaritenga whakahaere rānei. I te tauira tārua, e hēke ana ngā kupu whakahau 4-bit e waru mō te katoa he 32 bit. Ka utaina e WR ngā rehita tuatahi, i te wā e neke ana te LATCH i te raraunga ki ngā rehita tuarua i runga i te whakaritenga EDGE/LEVEL. [1]

MAX456EQH Whakahaere Whakawhiti me te Whakahaere

E tautoko ana te MAX456 i te whakahaere pātea 7-bit me te whakahaere tārua 32-bit. Kāore e whakamahi ngā mōhiohio e rua i te huinga katoa o ngā waehere whakahau, nā reira me whai ngā here waehere kaupapa. [1]

Whakahaere Pātea

Tūhono te SER/PAR = LOW. Ka whiriwhiria e A2–A0 te pātū ā mātou, ā, ka whiriwhiria e D3–D0 he whakauru, he mahi whakahaere rānei. Ka utaina te raraunga i te pito teitei o WR. [1]

D3–D0	Mahi-Pātea Mahi
0000–0111	Tūhono te pātū whakawhiti kua whiriwhiria ki IN0–IN7
1000	Tūhono te whakauru pātū kua whiriwhiria ki te DGND
1001	Kaua e whakamahi i te tauira pātea
1010	Kaua e whakamahi i te tauira pātea
1011	Kati te pātū whakawhiti kua whiriwhiria, ā, pupuri i ngā ihirangi tuarua
1100	Tīmata te pātū whakawhiti kua whiriwhiria, he whakaora i tōna huarahi hono i mua
1101	Kati ngā pātū katoa, ā, kaua e huri i ngā rehita tuarua
1110	Tīmata ngā pātū katoa, he whakaora i ngā huarahi hono i mua
1111	Komihana Software-LATCH

Ko ngā waehere 1001 me 1010 e whakaritea ana mō ngā mahi mō te tauira tārua, ā, kāore e taea te whakamahi i te tauira pātea. Ko te whakahau 1100 ka noho hei whakahau pātea mō te whakahiato i te pātū whakawhiti kua whiriwhiria me te whakaora i tōna hononga i mua. [1]

Whakahaere Tārua

Tūhono te SER/PAR = HIGH. Ka huri 32 bit ma roto i te SER IN mā te whakamahi i a WR hei poraka tārua. Ko te whak format raraunga ko D3–D0 mo te OUT0 i te tuatahi, ā, ka haere mai te OUT1 ki te OUT7. I muri i te utunga o ngā 32 bit, kāore te whakamahi i te LATCH hei tuku i te raraunga tuatahi ki ngā rehita tuarua e whai ana. [1]

D3–D0	Mahi-Tārua Mahi
0000–0111	Tūhono te putanga kua whiriwhiria ki IN0–IN7
1000	Tūhono te whakauru pātū kua whiriwhiria ki te whenua
1001	Tīmata te pātū whakawhiti kua whiriwhiria, ā, tūhono i tōna whakauru ki te whenua
1010	Kati te pātū whakawhiti kua whiriwhiria, ā, penaina te 1010 ki te rehita tuarua
1011–1111	Kaua e whakamahi i te tauira tārua

Ko ngā waehere anake 0000 ki 1010 he waehere kaha mō te tauira tārua. Ko ngā waehere 1011–1111 ka aukati i te mau i te tuarua ake, ā, kāore e taea te whakamahi. [1]

Tauira Whakawhiti

Hei tūhono i te IN5 ki te OUT2 i te tauira pātea, tūhono te A2–A0 = 010 me D3–D0 = 0101, kātahi ka tono i te WR me te LATCH e hiahiatia ana. Mēnā kua whakakorehia te OUT2 i mua, ā, me whakahokia tōna huarahi i mua, whakamahia te whakahau pātea 1100. [1]

Pōwhiri me Tirohanga Latch

Ko te whakahau hiko ka whakakore i ngā putanga pātū katoa i te tīmatanga, engari kāore e whakatakoto i te matrix whakawhiti ki te āhua huarahi kua tautuhia. Tuhia ngā hono e hiahiatia ana i mua i te whakatuwheratanga i ngā pātū. I te wā e tiketike ana te EDGE/LEVEL, ka whakahou ngā raraunga tuarua i te pito teitei o te LATCH. I te wā e iti ana te EDGE/LEVEL, ka whakahou te rehita tuarua i te wa e iti ana te LATCH. [1]
