1 / 6 page  UNISONIC TECHNOLOGIES CO., LTD U74HCT373 CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R502-655.A 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 TSSOP-20 ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing U74HCT373L-P20-R U74HCT373G-P20-R TSSOP-20 Tape Reel U74HCT373L-P20-T U74HCT373G-P20-T TSSOP-20 Tube |
