SN74LVC573AQDWRQ1

八路透明D类锁存器 OCTAL TRANSPARENT D-TYPE LATCH

description/ordering information

The SN74LVC573A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCCoperation.

This device features 3-state outputs designed specifically for driving highly capacitive or relatively

low-impedance loads. It is particularly suitable for implementing buffer registers, input/output I/O ports,

bidirectional bus drivers, and working registers.

While the latch-enable LE input is high, the Q outputs follow the data D inputs. When LE is taken low, the Q outputs are latched at the logic levels at the D inputs.
