74HC374 8 D-Flip-Flop With 3-Output State IC (74374 IC) DIP-20 Package

Description

74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC374 is one of them. 74HC374 ICs contain eight positive-edge-triggered D-type flip-flops with 3-Output states i.e. High, Low, and High Impedance. Which is designed specifically for driving highly capacitive or relatively low-impedance loads. High Impedance comes to active low enable pin of these ICs where output-enable (OE)’ input places the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. (OE)’ does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

The 74HC374 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 14 ns. They can drive 10 LS-TTL loads at a time. Which means that the output pin of D-type flip-flop can drive 10 TTL based Low-Power Schottky( LS ) input pins. They can provide 6 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 35 mA per output pin and 70 mA for overall pins in between 0 V to VCC.
