Description

The SN54LVC574A octal edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V V_CC operation and the SN74LVC574A octal edge-triggered D-type flip-flop is designed for 1.65-V to 3.6-V V_CC operation.

These devices SN54LVC574A feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
