Latch Multiplexed 3-ST 12-CH D-Type 56-Pin SSOP
description:
The ’ABTH162260 are 12-bit to 24-bit multiplexed D-type latches used in applications where two separate data
paths must be multiplexed onto, or demultiplexed from, a single data path. Typical applications include
multiplexing and/or demultiplexing of address and data information in microprocessor or bus-interface
applications. These devices are also useful in memory-interleaving applications.
Three 12-bit I/O ports (A1–A12, 1B1–1B12, and 2B1–2B12) are available for address and/or data transfer. The
output-enable (OE1B, OE2B, and OEA) inputs control the bus-transceiver functions. The OE1B and OE2B
control signals also allow bank control in the A-to-B direction.
Address and/or data information can be stored using the internal storage latches. The latch-enable (LE1B,
LE2B, LEA1B, and LEA2B) inputs are used to control data storage. When the latch-enable input is high, the
latch is transparent. When the latch-enable input goes low, the data present at the inputs is latched and remains
latched until the latch-enable input is returned high.
The B-port outputs, which are designed to sink up to 12 mA, include equivalent 25-Ω series resistors to reduce
overshoot and undershoot.
