Texas Instruments SN74AHC574 D-Type Flip-Flops

Texas Instruments SN74AHC574 D-Type Flip-Flops are octal edge-triggered devices with 3-state outputs. These flip-flops are designed specifically for driving highly capacitive or relatively low-impedance loads. The SN74AHC574 devices are well-suited for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. These D-type flip-flops operate with a 2V to 5.5V VCC supply voltage range and a temperature range of -40°C to 125°C. The SN74AHC574 flip-flops are compliant with MIL-PRF-38535. These flip-flops are ideal for use with smart grids, TVs, set-top boxes, audio equipment, servers, surveillance cameras, network switches, and infotainment systems.
