MM74HCT573WM集成电路（IC）的锁存器规格书PDF中文资料

General Description

The MM74HCT573 octal D-type latches and MM74HCT574 octal D-type flip-flop advanced silicon-gate CMOS technology, which provides the inherent benefits of low power consumption and wide power supply range, but are LS-TTL input and output characteristic and pin-out compatible. The 3-STATE outputs are capable of driving 15 LS-TTL loads. All inputs are protected from damage due to static discharge by internal diodes to VCC and ground.

■ Typical propagation delay: 18 ns

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA maximum

■ Compatible with bus-oriented systems

■ Output drive capability: 15 LS-TTL loads
