Description

74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC273 is one of them. 74HC273 ICs contain eight positive-edge-triggered D-type flip-flops with single-rail outputs with individual data input to each flip-flop. And also provide direct active low clear ( CLR’ ) input.

The 74HC273 ICs have a wide operating range of VCC from 2 V to 6 V. Maximum current consumption is 80 uA through Icc and 1 uA per input pin. And the propagation delay is 12 ns. They can drive 10 LS-TTL loads at a time. This means that the output pin of the D-type flip-flop can drive 10 TTL based Low-Power Schottky( LS ) input pins. They can provide 4 mA on outputs at 5 V VCC. They allow inputs and outputs up to VCC. Recommended operating VCC is 5 V. Load Current can reach up to 25 mA per output pin and 50 mA for overall pins in between 0 V to VCC.

Applications:

Shift Registers
Buffer Or Storage Register
Pattern Generators
