description
This 1-bit to 4-bit address register/driver is
designed for 1.65-V to 3.6-V V_CC 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.
