SN74HCT273DW

SN74HCT273DW Description

The SN74HCT273DW from Texas Instruments is a high-speed, 8-bit D-type flip-flop with master reset, designed for reliable data storage and transfer in digital systems. Housed in a 20-pin SOIC package, this device operates within a 4.5V to 5.5V supply range, making it compatible with standard TTL and CMOS logic levels. With a 37 MHz clock frequency and a max propagation delay of 29ns @ 5.5V, it ensures efficient performance in timing-critical applications. The positive-edge triggering mechanism synchronizes data transitions, while the master reset function provides immediate clearing of all outputs. Its low quiescent current (8 µA) and RoHS3 compliance make it suitable for power-sensitive and environmentally conscious designs.
