SN74HCT573NSR

八路透明D类锁存器具有三态输出 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS

description/ordering information

These octal transparent D-type latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The ’HCT573 devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Operating Voltage Range of 4.5 V to 5.5 V

High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads

Low Power Consumption, 80-µA Max ICC

Typical tpd = 21 ns

±6-mA Output Drive at 5 V

Low Input Current of 1 µA Max

nputs Are TTL-Voltage Compatible

Bus-Structured Pinout
