U74AHCT373

UNISONIC TECHNOLOGIES CO., LTD U74AHCT373 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS CMOS IC  DESCRIPTION The U74AHCT373 is an octal transparent D-type latch with 3-state outputs and 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 8.5ns at VCC=5V, CL=15pF  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHCT373L-D20-T U74AHCT373G-D20-T U74AHCT373L-P20-R U74AHCT373G-P20-R Package DIP-20 TSSOP-20 Packing Tube Tape Reel U74AHCT373G-D20-T  MARKING (1)Packing Type (2)Package Type (3)Green Package (1) T: Tube, R: Tape Reel (2) D20: DIP-20, P20: TSSOP-20 (3) G: Halogen Free and Lead Free, L: Lead Free www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-685.B U74AHCT373  PIN CONFIGURATION OE 1 1Q 2 1D 3 2D...
