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
