Texas Instruments SN54ABT16245A SN74ABT16245A Data Manual
Summary
The SN/SN74ABT16245A is a high-performance, 16-bit noninverting transceiver designed for robust and efficient synchronous two-way data communication across multiple buses. This manual details its advanced EPIC-IIB™ BiCMOS architecture, which minimizes power dissipation and switching noise. It provides comprehensive technical specifications, operational guidelines, package options (including surface mount and flat packages), and performance guarantees for both military (-55°C to 125°C) and industrial grades. This component is ideal for electronics engineers building high-speed systems requiring reliable data transmission between separate logic buses.

DESCRIPTION
The 'ABT16245A devices are 16-bit noninverting 3-state transceivers designed for synchronous two-way
communication between data buses. The control-function implementation minimizes external timing
requirements.
These devices can be used as two 8-bit transceviers or one 16-bit transceiver. They allow data transmission from
the bus to the bus or from the bus to the bus, depending on the logic level at the direction-control (DIR)
input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
When VCC is between and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impendance state above 2.1 V, OE should be tied to VCC through pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT16245A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16245A is characterized for operation from –40°C to 85°C.

Frequently Asked Questions
What is required to maintain high impedance when V is above 2.1V?
To ensure the high-impedance state above 2.1 V, the Output-Enable (OE) input must be tied to V through a pull-up resistor.
How does data flow between A and B buses work?
The device allows transmission from the A bus to the B bus or vice versa, depending on the logic level at the direction-control (DIR) input.
What is the primary function of the Output-Enable (OE) input?
The OE input can be used to disable the entire device, which effectively isolates the two data buses.
What are the operational temperature ranges for these transceivers?
The SN54ABT16245A is rated for –55°C to 125°C, while the SN74ABT16245A operates from –40°C to 85°C.
