description
This 1-bit to 4-bit address register/driver is
designed for 1.65-V to 3.6-V VCC operation.
The device is ideal for use in applications in which
a single address bus is driving four separate
memory locations. The SN74ALVCH162831 can
be used as a buffer or a register, depending on the
logic level of the select (SEL) input.
When SEL is logic high, the device is in the buffer
mode. The outputs follow the inputs and are
controlled by the two output-enable (OE) inputs.
Each OE controls two groups of nine outputs.
When SEL is logic low, the device is in the register
mode. The register is an edge-triggered D-type
flip-flop. On the positive transition of the clock
(CLK) input, data set up at the A inputs is stored
in the internal registers. OE controls operate the
same as in buffer mode.
When OE is logic low, the outputs are in a normal
logic state (high or low logic level). When OE is
logic high, the outputs are in the high-impedance
state.

SN74ALVCH162831
1-BIT TO 4-BIT ADDRESS REGISTER/DRIVER
WITH 3-STATE OUTPUTS
SCES084F – AUGUST 1996 – REVISED JUNE 1999
description (continued)
SEL and OE do not affect the internal operation of the flip-flops. Old data can be retained or new data can be
entered while the outputs are in the high-impedance state.
The outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot
and undershoot.
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.
The SN74ALVCH162831 is characterized for operation from –40°C to 85°C.
