description
The ’ABT16265 is a 12-bit to 24-bit multiplexed
transceiver used in applications where two
separate data paths must be multiplexed onto, or
demultiplexed from, a single data path. Typical
applications
include
demultiplexing of address and data information in
microprocessor- or bus-interface applications.
This device is also useful in memory-interleaving
applications.
multiplexing
and/or
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. These control signals also
allow byte-control of the most significant byte and least significant byte for each bus.
Active bus-hold circuitry is provided to hold unused or floating inputs at a valid logic level.
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.
The SN74ABT16265 is packaged in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16265 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16265 is characterized for operation from –40
°
C to 85
°
C.
