SN74ALVCH162841
20-BIT BUS-INTERFACE D-TYPE LATCH
WITH 3-STATE OUTPUTS
SCES088D – OCTOBER 1996 – REVISED JUNE 1999
description (continued)
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC 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 inputs at a valid logic level.
The SN74ALVCH162841 is characterized for operation from –40°C to 85°C.
