U74HCT373 - OCTAL TRANSPARENT D-TYPE LATCHES

General Description

The U74HCT373 is an octal transparent D-type latch with 3-state outputs, and it has 8 channels.

outputs follow the D inputs.

When OE is low and LE is low, the Q outputs are latched at the logic levels of the D inputs.

Key Features

  • S.
  • Inputs are TTL-Voltage Compatible.
  • Operate from 4.5V to 5.5V.
  • Inputs Accept Voltages to 5.5V.
  • Max tPD of 21ns at VCC=5.5V, CL=50pF.
  • Typ. VOL< 0.26V at VCC=4.5V, IOL=6mA, TA=25°C.
  • Typ. VOH> 3.94V at VCC=4.5V, IOH=-6mA, TA=25°C.

UNISONIC TECHNOLOGIES CO., LTD U74HCT373 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS  DESCRIPTION The U74HCT373 is an octal transparent D-type latch with 3-state outputs, and it has 8 channels. When the OE input is low and the LE input is high, the Q outputs follow the D inputs. When OE is low and LE is low, the Q outputs are latched at the logic levels of the D inputs. When the OE input is high, the outputs are in the high-impedance. The OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
