IDT74ALVC162831
which a single address bus is driving four separate memory locations.
The ALVC162831 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)
controls. 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 a high-
impedance state.
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 ALVC162831 has series resistors in the device output structure
which will significantly reduce line noise when used with light loads. This
driver has been designed to drive ±12mA at the designated threshold
levels.
