Product details

Overview

SN74LVC162244ADLG4 from Texas Instruments is a 16-bit noninverting 3-state buffer/driver with four independent 4-bit sections, operating from 1.65 V to 3.6 V, supporting 5.5-V-tolerant inputs and delivering ±12 mA output drive at 3.3 V - used for bus isolation and level translation in memory address and clock distribution systems.

For engineers reviewing the SN74LVC162244ADLG4 datasheet, SN74LVC162244ADLG4 pinout, SN74LVC162244ADLG4 application, or SN74LVC162244ADLG4 equivalent, key selection criteria include 3-state enable control per 4-bit group, Ioff support for live insertion, 26-Ω on-die series output termination, and compatibility with mixed-voltage (3.3 V/5 V) system interfacing.

Technical Context

This device implements four independent 4-bit noninverting buffers, each with an active-low output-enable (OE) input controlling all four Y outputs simultaneously. Each section features true (noninverting) logic and symmetrical enable timing.

It uses advanced LVC CMOS technology enabling operation across 1.65–3.6 V while maintaining 5.5-V input tolerance - allowing direct connection to legacy 5-V logic without external level shifters. The integrated 26-Ω series output resistance suppresses overshoot/undershoot without requiring external termination.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	1.65 V to 3.6 V - enables single-supply operation in modern low-voltage digital systems including battery-powered and mixed-voltage designs.
Input Voltage Tolerance	Up to 5.5 V - allows safe interfacing with 5-V TTL or CMOS sources without clamping diodes or external protection.
Max Propagation Delay	4.4 ns at 3.3 V - supports high-speed data routing in memory address drivers and clock fanout applications up to ~100 MHz.
Output Drive Strength	±12 mA at 3.3 V - sufficient to drive moderate capacitive loads (e.g., PCB traces, multiple CMOS inputs) without external buffers.
Ioff Support	Active at VCC = 0 V - prevents back-drive current during partial power-down, enabling hot-swap capability in modular systems.
ESD Protection	2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for handling and board-level reliability.
Output Termination	Integrated 26-Ω series resistor - eliminates need for discrete series resistors, reducing BOM count and layout area for signal integrity.

Pinout & Package

SN74LVC162244ADLG4 is packaged in SSOP-48 (DL package), body size 15.88 × 7.49 mm, with 0.5-mm lead pitch and gull-wing leads suitable for surface-mount reflow assembly.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE	Active-low output enable inputs	Each controls one 4-bit output group (Y1–Y4); asserted low enables corresponding Y outputs, high places them in high-impedance state.
1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4	Buffer input terminals	16 total inputs accepting 5.5-V-tolerant signals; grouped into four 4-bit channels aligned with respective OE pins.
1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4	Noninverting 3-state output terminals	16 buffered outputs with integrated 26-Ω series resistance; driven high/low when enabled, high-Z when OE is high.
VCC (Pins 7, 18, 31, 42)	Power supply	Four dedicated VCC pins distributed across package to minimize IR drop and improve noise immunity in high-speed switching.
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins provide low-inductance return paths, critical for stable operation and EMI reduction in multi-bit drivers.

Key Features

Feature	Design Value
Wide VCC range	1.65 V to 3.6 V operation enables compatibility with 1.8-V, 2.5-V, and 3.3-V logic families in same design.
5.5-V tolerant inputs	Allows direct interface to 5-V legacy logic without external level translators or voltage dividers.
On-die 26-Ω output series resistance	Reduces signal ringing and overshoot on PCB traces, eliminating need for discrete termination resistors.
Ioff partial-power-down protection	Prevents damaging current flow when VCC = 0 V, supporting hot-plug and modular backplane architectures.
Low ground bounce / output undershoot	Typical VOLP < 0.8 V and VOHV > 2 V at 3.3 V - ensures clean signal edges and reduces crosstalk in dense layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC162244ADGGR	TSSOP-48 package (12.50 × 6.10 mm), same electrical specs, identical pinout, RoHS-compliant NiPdAu finish.	Better suited for automated SMT assembly with tighter board space constraints due to smaller footprint than SSOP.	Select SN74LVC162244ADGGR when board real estate is limited and reflow profile supports TSSOP.
SN74LVC162244ADGVR	TVSOP-48 package (9.70 × 4.40 mm), same functionality and timing, thinner profile (1.2 mm max height), identical pinout.	Preferred for ultra-thin portable or stacked-module designs where Z-height is constrained.	Choose SN74LVC162244ADGVR for space-constrained, low-profile applications requiring same performance in smaller volume.

Compared with SN74LVC162244ADLG4, the TSSOP and TVSOP variants offer identical electrical behavior but reduce PCB area and/or component height - enabling denser layouts without compromising drive strength, voltage tolerance, or Ioff capability.

FAQ

What is the maximum operating temperature for SN74LVC162244ADLG4?

The SN74LVC162244ADLG4 is rated for operation from –40°C to +125°C ambient temperature, making it suitable for extended industrial and automotive under-hood applications where thermal stability is critical. This rating is validated per JEDEC JESD78 latch-up testing and confirmed in the Recommended Operating Conditions table of the official datasheet.

Does SN74LVC162244ADLG4 support live insertion or hot-swap?

Yes, SN74LVC162244ADLG4 supports live insertion via its Ioff feature, which disables outputs and blocks current flow when VCC = 0 V. This prevents back-drive damage during partial power-down - essential for modular backplanes, hot-pluggable cards, and redundant power systems where individual modules may be inserted or removed while powered.

Can SN74LVC162244ADLG4 interface directly with 5-V logic inputs?

Yes, SN74LVC162244ADLG4 accepts input voltages up to 5.5 V regardless of VCC (1.65–3.6 V), enabling direct connection to 5-V TTL or CMOS outputs without level-shifting circuitry. This is explicitly specified in the "Inputs Accept Voltages to 5.5 V" feature and verified in the Absolute Maximum Ratings and Recommended Operating Conditions tables.

What is the purpose of the four separate OE pins on SN74LVC162244ADLG4?

The four active-low OE pins (1OE–4OE) independently control four 4-bit output groups, allowing selective bus isolation. For example, OE1 can disable outputs 1Y1–1Y4 while keeping 2Y1–2Y4 active - enabling flexible memory banking, clock gating per peripheral, or dynamic signal routing without full device shutdown.

Is external termination required for SN74LVC162244ADLG4 outputs?

No, SN74LVC162244ADLG4 integrates 26-Ω series output resistors on all Y pins, designed to match typical PCB trace impedances and suppress overshoot/undershoot. This eliminates the need for discrete series resistors, reducing BOM cost and layout complexity while maintaining signal integrity on moderate-length traces.
