SN74AVCH374
OCTAL POSITIVE-EDGE-TRIGGERED D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUTS
SCES267D – APRIL 1999 – REVISED FEBRUARY 2000
3–78
POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
OE does not affect internal operations of the latch. 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 pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74AVCH374 is characterized for operation from –40
°C to 85°C.
