MC74HCT373AFELG集成電路（IC）的鎖存器規(guī)格書PDF中文資料

MC74HCT373AFELG屬于集成電路（IC）的鎖存器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74HCT373AFELG鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

Octal 3-State Noninverting Transparent Latch with LSTTL-Compatible Inputs

High?Performance Silicon?Gate CMOS

The MC74HCT373A may be used as a level converter for interfacing TTL or NMOS outputs to High?Speed CMOS inputs.

The HCT373A is identical in pinout to the LS373.

The eight latches of the HCT373A are transparent D?type latches.

While the Latch Enable is high the Q outputs follow the Data Inputs.

When Latch Enable is taken low, data meeting the setup and hold times becomes latched.

? Output Drive Capability: 15 LSTTL Loads

? TTL/NMOS?Compatible Input Levels

? Outputs Directly Interface to CMOS, NMOS, and TTL

? Operating Voltage Range: 4.5 to 5.5 V

? Low Input Current: 1.0 A

? In Compliance with the Requirements Defined by JEDEC Standard

No. 7 A

? Chip Complexity: 196 FETs or 49 Equivalent Gates

? These Devices are Pb?Free and are RoHS Compliant
