What are the key features of 74ABT162244DGGR?
- 16-bit 3-state bus driver with two independent 8-bit output-enable controls for flexible bidirectional bus architecture
- ABT-series high-speed output drive up to 64 mA per output for driving large capacitive loads on backplane or memory bus lines
- 48-pin TSSOP package enabling dense PCB layouts for 16-bit data bus buffering between processor and memory subsystems
What is 74ABT162244DGGR used for?
The 74ABT162244DGGR is used to buffer and drive 16-bit data buses between processors, FPGAs, and SRAM or Flash memory banks where bus loading exceeds the drive capability of the source device. Its ABT logic family speed and 64 mA output drive make it suitable for industrial controllers, network switch line cards, and VME or PCI backplane systems operating at 5 V. The two independent 8-bit output-enable signals allow designers to implement byte-wide or word-wide bus multiplexing without additional logic gates.

Frequently Asked Questions
How many output channels and what drive current does the 74ABT162244DGGR provide?
The 74ABT162244DGGR provides 16 output channels organized as two 8-bit banks, each with an independent active-low output-enable pin. Each output can source or sink up to 64 mA, which is sufficient to drive heavily loaded 5 V backplane buses with multiple receivers without signal integrity degradation.
What supply voltage does the 74ABT162244DGGR require, and how does ABT logic compare to LVTTL in speed?
The device operates from a 4.5 V to 5.5 V supply, making it a 5 V part. ABT (Advanced BiCMOS Technology) logic achieves propagation delays typically under 3.5 ns from input to output, which is faster than standard 74HCT parts at 7–10 ns and comparable to LVTTL devices, making it appropriate for bus frequencies up to 100 MHz.
For a 16-bit SRAM interface on a DSP board, how does the 74ABT162244DGGR simplify the layout in a 48-pin TSSOP package?
The 48-pin TSSOP package has a body width of 6.1 mm and 0.5 mm pin pitch, fitting a 16-bit unidirectional buffer into a footprint under 200 mm². The two 8-bit output-enable controls allow the designer to independently enable high byte and low byte, eliminating 2 external AND gates and reducing trace routing complexity compared to using two separate 8-bit buffers with separate enables.
What logic family alternatives exist if 74ABT162244DGGR goes out of production?
Compatible 16-bit 3-state buffer alternatives in similar packages include the 74ALVT16244 for 2.5 V to 3.3 V systems, and the 74BCT16244 for 5 V designs with BiCMOS outputs. Electrically, any 16-bit buffer with 48-pin TSSOP pinout, two 8-bit output-enables, and at least 32 mA drive per output can serve as a functional drop-in replacement, though timing re-verification at system frequency is required.
