74ABT162244DL,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT162244 is a 16-bit buffer and line driver featuring integrated 30 Ω series termination resistors and 3-state outputs. It operates on a supply voltage range of 4.5 V to 5.5 V using BiCMOS technology. The device supports four independent output enables, allowing configuration as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It includes IOFF circuitry for partial power-down applications to prevent backflow current. The component provides high-speed performance with propagation delays ranging from 1.0 ns to 4.4 ns depending on the transition direction.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 30 Ω series termination resistors for signal integrity

• Power-up 3-state functionality ensures safe initialization
• Multiple VCC and GND pins minimize switching noise

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operation
• Live insertion and extraction systems
• Direct interface with TTL levels

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the datasheet revision history. The source document indicates that the SSOP48 variant (74ABT162244DL) was removed in version 7 of the data sheet. Ensure the ordered part matches the currently supported TSSOP48 (SOT362-1) package to avoid compatibility issues with legacy ordering suffixes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 5 V logic interfaces requiring built-in series termination to reduce reflections. The BiCMOS technology offers higher drive capability compared to standard CMOS options. Verify that the application environment remains within the specified -40 °C to +85 °C temperature range and utilizes the required 4.5 V to 5.5 V supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ABT logic family, which utilizes Advanced BiCMOS Technology. This family is designed for high-speed applications requiring direct interfacing with TTL levels. The 74ABT162244 specifically addresses bus interface requirements by providing 16-bit buffering with integrated termination, distinguishing it from standard non-terminated buffers in the same series.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet revision history confirms that the 74ABT162244DL (SSOP48) has been removed. Designers must transition to the 74ABT162244DGG (TSSOP48). No other functional substitutes are listed in the provided documentation.
