Texas Instruments 74HC373 8 D-Latch With 3-Output State IC (74373 IC) DIP-20 Package

74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC373 is one of them. 74HC373 ICs contain eight D-type latches with 3-Output states i.e. High, Low, and High Impedance. 74HC373 provides Latch-Enable (LE) input pin and when it’s high, the Q outputs follow the data (D) inputs. When LE is low, the device does not change the previous logic. ts. A buffered output-enable (OE)’ input can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. OE’ does not affect the internal stored logic.

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 13 ns. They can drive 15 LS-TTL loads at a time. This means that the output pin of a D-type flip-flop can drive 15 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.
