description
The ’ABTH16460 are 4-bit to 1-bit multiplexed
registered transceivers used in applications
where four 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 also
are useful in memory-interleaving applications.
Five 4-bit I/O ports (1A–4A, 1B1–4, 2B1–4, 3B1–4, and 4B1–4) are available for address and/or data transfer.
The output-enable (OEB, OEB1–OEB4, and OEA) inputs control the bus-transceiver functions. These control
signals also allow 4-bit or 16-bit control, depending on the OEB level.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

description (continued)
Address and/or data information can be stored using the internal storage latches/flip-flops. The latch-enable
(LEB1–LEB4,LEBA, andLEAB1–LEAB4)andclock/clock-enable(CLK/CLKEN) inputs are used to control data
storage. When either one of the latch-enable inputs is high, the latch is transparent (clock is a don’t care as long
as the latch enable is high). When the latch-enable input goes low (providing that the clock does not transit from
low to high), the data present at the inputs is latched and remains latched until the latch-enable input is returned
high. When the clock enable is low and the corresponding latch enable is low, data can be clocked on the
low-to-high transition of the clock. When either the clock enable or the corresponding latch enable is high, the
clock is a don’t care.
Four select pins (SEL0, SEL1, CE_SEL0, and CE_SEL1) are provided to multiplex data (A port), or to select
one of four clock enables (B port). This allows the user the flexibility of controlling one bit at a time.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
When V
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V
the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABTH16460 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABTH16460 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51.
