Description
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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  FEATURES * 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  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HCT373L-D20-T U74HCT373G-D20-T U74HCT373L-S20-R U74HCT373G-S20-R U74HCT373L-P20-R U74HCT373G-P20-R Package DIP-20 SOP-20 TSSOP-20 CMOS IC Packing Tube Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-655.D U74HCT373  MARKING DIP-20  PIN CONFIGURATION CMOS IC SOP-20 / TSSOP-20  FU...
