3 Description

The SN54LVC573A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC573A octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively low- impedance loads. They are particularly suitable for implementing buffer registers, input/output (I/O) ports,bidirectional bus drivers, and working registers.
