Nexperia USA Inc. 74LVT162244BDGG:11

Overview

74LVT162244BDGG:11 from Nexperia is a 3.3 V 16-bit 3-state buffer/driver with integrated 30 Ω series output termination resistors, four independent output-enable inputs (1OE–4OE), bus-hold inputs eliminating external pull-ups, and ±12 mA drive capability. It operates across 2.7 V to 3.6 V supply and supports -40 °C to +85 °C ambient, used in high-speed parallel bus interfacing between LVTTL/CMOS logic domains.

For engineers reviewing the 74LVT162244BDGG:11 datasheet, 74LVT162244BDGG:11 pinout, 74LVT162244BDGG:11 application, or 74LVT162244BDGG:11 equivalent, key selection criteria include its 30 Ω on-die termination, quad 4-bit enable control, bus-hold input retention, IOFF power-down isolation, and TSSOP48 package compatibility with dense PCB layouts.

Technical Context

This BiCMOS device implements four independent 4-bit 3-state buffers, each controlled by a dedicated active-low output-enable input (1OE–4OE). Each output includes a 30 Ω series resistor for impedance matching and reduced signal reflections on transmission lines.

Inputs are overvoltage tolerant up to 5.5 V and feature bus-hold circuitry that maintains logic state without external biasing. The IOFF circuit enables partial power-down operation when VCC = 0 V, limiting leakage to ±100 μA across all I/O pins.

FAQ

Can the 74LVT162244BDGG:11 be used with a 5 V microcontroller driving its inputs?

Yes. Its inputs are overvoltage tolerant up to 5.5 V, allowing direct connection to 5 V logic without level shifters. The device operates from 2.7 V to 3.6 V supply, so VCC must remain within that range. Input clamping current is limited to ±50 mA per pin under overvoltage conditions, and internal protection diodes safely shunt excess voltage to VCC or GND.

What is the purpose of the eight GND pins in the TSSOP48 package?

The eight GND pins reduce ground loop inductance and distribute return current paths, minimizing ground bounce during simultaneous 16-bit switching. This improves signal integrity and noise margin-critical for sub-5 ns propagation delays. Layout best practice recommends connecting all GND pins directly to a solid ground plane with multiple vias.

Does the bus-hold feature eliminate all need for external pull-up resistors?

Yes-for unused or undriven inputs. Bus-hold circuitry provides ±75 μA to ±135 μA of active current to retain the last valid logic state, preventing floating inputs and associated noise sensitivity. It does not replace pull-ups for open-drain or wired-OR configurations where active LOW assertion is required.

How does the 30 Ω series termination affect PCB layout?

The 30 Ω resistor is placed internally in series with each output, enabling source termination for point-to-point traces routed to a matched 50 Ω load. This eliminates the need for 16 discrete 30 Ω resistors, reduces parasitic inductance, and simplifies layout-especially beneficial in dense, high-pin-count interconnects like memory modules or backplanes.
