Product details
Overview
74ALVCH162244DGG:5 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-State outputs, integrated 30Ω series termination resistors on all outputs, bus hold circuitry on all inputs, and operation across 1.2V–3.6V supply range. It supports high-speed data routing in low-voltage memory and bus interfaces, with typical propagation delay of 2.7 ns at 3.3V/50pF.
For engineers reviewing the 74ALVCH162244DGG:5 datasheet, 74ALVCH162244DGG:5 pinout, 74ALVCH162244DGG:5 application, or 74ALVCH162244DGG:5 equivalent, key selection criteria include 30Ω output termination, bus hold functionality, 48-pin TSSOP package, and dual 3-State enable control for independent 4-bit group management.
Technical Context
The 74ALVCH162244DGG:5 implements four independent 4-bit non-inverting buffers, each with dedicated active-low output enable (1OE–4OE) and internal 30Ω series resistors in both HIGH and LOW output states. Its Si-gate CMOS architecture ensures compatibility with TTL input levels while enabling direct interface to 1.2V–3.6V logic systems.
Bus hold circuitry actively maintains valid logic states on floating or unused inputs without external pull resistors, reducing BOM count and layout complexity. The device features low-inductance multiple VCC and GND pins to minimize ground bounce and noise in high-density PCB layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVCH162244DGGR | TI version; identical pinout, same 30Ω termination and bus hold; slightly higher ICC max (60 µA vs 40 µA). | Qualified to AEC-Q100 Grade 2; preferred for automotive under-hood applications requiring extended temperature validation. | Select SN74ALVCH162244DGGR when AEC-Q100 compliance is mandatory and TI sourcing is preferred. |
| 74LVC162244ADGG | No integrated 30Ω resistors; lower drive strength (24 mA vs 32 mA); same bus hold and 1.65V–3.6V VCC range. | Used where external termination is already implemented or where lower power (CPD = 15 pF) outweighs termination convenience. | Choose 74LVC162244ADGG when board-level termination exists or when minimizing quiescent current is critical. |
Compared with SN74ALVCH162244DGGR and 74LVC162244ADGG, the 74ALVCH162244DGG:5 uniquely combines on-die 30Ω termination, ultra-low input capacitance (5 pF), and guaranteed bus hold across –40°C to +85°C - making it optimal for compact, high-reliability industrial and computing bus interfaces where layout area and signal integrity are constrained.

FAQ
What is the operating voltage range supported by the 74ALVCH162244DGG:5?
The 74ALVCH162244DGG:5 operates across a wide supply voltage range of 1.2V to 3.6V, supporting direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic families. This allows seamless integration into mixed-voltage systems without external level shifters, and its performance specifications - including propagation delay and drive strength - are guaranteed across this full range per JEDEC standard no. 8-1A.
Does the 74ALVCH162244DGG:5 include built-in termination resistors?
Yes, the 74ALVCH162244DGG:5 integrates a precise 30Ω series resistor on each of its 16 outputs, in both HIGH and LOW output states. This eliminates the need for 16 discrete external termination resistors, reduces PCB footprint, improves signal integrity on short-to-medium-length traces, and simplifies layout - especially in high-density memory and bus applications where reflection control is critical.
How does the bus hold feature function on the 74ALVCH162244DGG:5?
The 74ALVCH162244DGG:5 includes active bus hold circuitry on all 16 data inputs, which maintains a valid logic HIGH or LOW state when inputs are floating or unterminated. It draws ±45 µA to ±175 µA (depending on VCC and input voltage), preventing metastability and eliminating the need for external pull-up or pull-down resistors - a key advantage during power-up, hot-swap events, or in modular backplane designs.
What package type is used for the 74ALVCH162244DGG:5?
The 74ALVCH162244DGG:5 is housed in a 48-pin Plastic Thin Shrink Small Outline Package (TSSOP) with 6.1 mm body width, designated SOT362-1. This fine-pitch surface-mount package supports high I/O density and automated assembly, and its eight GND and four VCC pins are strategically placed to minimize ground bounce and supply noise in high-speed digital systems.
Can the 74ALVCH162244DGG:5 be used in automotive applications?
The 74ALVCH162244DGG:5 is rated for operation from –40°C to +85°C and complies with JEDEC standards, making it suitable for many automotive cabin and infotainment applications. However, it is not AEC-Q100 qualified. For under-hood or safety-critical automotive use, engineers should consider the pin-compatible SN74ALVCH162244DGGR, which carries AEC-Q100 Grade 2 qualification and extended reliability testing.
