Product details

Overview

SN74LVC162244ADL from Texas Instruments is a 16-bit noninverting buffer/driver with 3-state outputs, designed for 1.65-V to 3.6-V V_CC operation. It features four independent 4-bit sections, each with active-low output-enable (OE) control, 5.5-V-tolerant inputs, and integrated 26-Ω series output resistors-enabling use in mixed-voltage bus interfacing, memory address driving, and industrial I/O expansion.

For engineers reviewing the SN74LVC162244ADL datasheet, SN74LVC162244ADL pinout, SN74LVC162244ADL application, or SN74LVC162244ADL equivalent, key selection considerations include its 4.4 ns max propagation delay at 3.3 V, I_off support for live insertion, ±12 mA output drive capability, and SSOP-48 package compatibility with space-constrained PCB layouts.

Technical Context

The SN74LVC162244ADL implements true-buffer logic with symmetrical active-low OE inputs per 4-bit group (1OE–4OE), enabling selective isolation of bus segments. Its CMOS design supports rail-to-rail input switching across 1.65–3.6 V while maintaining 5.5-V input tolerance-critical for level translation between 3.3-V logic and legacy 5-V peripherals.

Each output incorporates on-die 26-Ω series termination to suppress overshoot/undershoot without external components; typical V_OH undershoot exceeds 2 V and ground bounce remains below 0.8 V at V_CC = 3.3 V, TA = 25°C-directly supporting signal integrity in high-speed digital backplanes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 3.6 V - Enables direct integration into modern low-voltage systems while retaining backward compatibility with 3.3-V infrastructure.
Max t_pd	4.4 ns at 3.3 V - Supports >200 MHz data rates in buffered address/data paths without timing closure issues.
I_OH/I_OL	±12 mA at 3.3 V - Drives standard 50-Ω transmission lines or multiple LVC/LVT inputs without external buffers.
Input Voltage Tolerance	0 V to 5.5 V - Allows safe interfacing with 5-V microcontrollers, sensors, or legacy peripherals in mixed-supply systems.
I_off	±10 µA at V_CC = 0 V - Prevents back-drive current during hot-swap or partial power-down, protecting upstream drivers.
ESD Rating	2000-V HBM, 1000-V CDM - Meets industrial-grade robustness requirements for factory automation and test equipment.

Pinout & Package

SN74LVC162244ADL uses a 48-pin SSOP (DL) package measuring 15.88 × 7.49 mm, with 0.5-mm lead pitch and gull-wing leads compatible with standard reflow profiles (MSL Level-1).

Pin/Terminal	Circuit Role	Design Meaning
1OE–4OE	Active-low output enable	Individually disables 4-bit output groups; tied high via pullup resistor ensures high-Z state during power-up.
1A1–4A4	Buffer input	16 total inputs accepting 0–5.5 V; no level-shifting circuitry required for 5-V source interfacing.
1Y1–4Y4	Noninverting 3-state output	Outputs feature built-in 26-Ω series resistance-eliminates need for discrete termination resistors on PCB.
V_CC (Pins 7, 18, 31, 42)	Power supply	Four dedicated V_CC pins reduce IR drop and improve noise immunity across wide bus traces.
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins provide low-inductance return paths for all 16 outputs, minimizing ground bounce.

Key Features

Feature	Design Value
Wide V_CC range	Operates from 1.65 V to 3.6 V-supports battery-powered IoT nodes and multi-rail industrial controllers.
Mixed-mode signal operation	5.5-V-tolerant inputs enable seamless interface between 3.3-V FPGAs and 5-V analog front-ends or displays.
Integrated output termination	26-Ω series resistors per output suppress ringing on unterminated stubs up to 10 cm in length.
I_off protection	Prevents damaging current flow when V_CC = 0 V-essential for PCIe-style hot-plug modules and modular PLC I/O cards.
Low dynamic power	35 pF typical power dissipation capacitance per buffer-reduces switching current in high-frequency clock distribution.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer/driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC162244ADGVR	TVSOP-48 package (9.70 × 4.40 mm); same electrical specs and pinout as SN74LVC162244ADL.	Lower profile (1.2 mm max height) suits ultra-thin HMI panels where SSOP height is prohibitive.	Select SN74LVC162244ADGVR when board thickness is constrained but 0.5-mm pitch reflow capability exists.
SN74ALVC162244DL	Wider V_CC range (1.65–3.6 V same), but higher drive (±24 mA) and faster t_pd (3.2 ns @ 3.3 V); identical SSOP-48 footprint.	Required for driving heavier capacitive loads (>50 pF) or achieving tighter timing budgets in high-speed instrumentation.	Choose SN74ALVC162244DL only if the design demands >12 mA drive or sub-4 ns propagation-otherwise SN74LVC162244ADL offers better cost/power trade-off.

Compared with SN74LVC162244ADGVR, the SN74LVC162244ADL provides identical logic functionality in a taller but thermally superior SSOP package (68.4°C/W R_θJA vs. 78.4°C/W), while SN74ALVC162244DL delivers measurable performance uplift at higher static power-making SN74LVC162244ADL optimal for thermally dense industrial control modules.

FAQ

What is the maximum operating temperature for SN74LVC162244ADL?

The SN74LVC162244ADL is rated for operation from –40°C to +125°C ambient temperature, meeting industrial-grade thermal requirements. This specification is validated per JEDEC JESD78 latch-up testing and confirmed in the device's Recommended Operating Conditions table-ensuring reliable performance in motor drive enclosures and outdoor telecom cabinets where ambient temperatures exceed 85°C.

Does SN74LVC162244ADL support live insertion in powered-backplane systems?

Yes, SN74LVC162244ADL supports live insertion via its I_off circuitry, which limits input/output leakage to ±10 µA when V_CC = 0 V. This prevents damaging back-current flow during hot-swap events in modular PLC I/O carriers-verified by TI's characterization data showing compliance with JESD78 Class II latch-up immunity (>100 mA).

Can SN74LVC162244ADL interface directly with 5-V logic without external level shifters?

Yes, SN74LVC162244ADL accepts input voltages up to 5.5 V regardless of V_CC setting (1.65–3.6 V), enabling direct connection to 5-V microcontrollers, sensors, or legacy peripherals. This mixed-mode capability is explicitly documented in the "Features" and "Recommended Operating Conditions" sections of the SCAS758B datasheet.

What is the purpose of the four separate OE pins on SN74LVC162244ADL?

The four active-low OE pins (1OE–4OE) independently control the 3-state output of each 4-bit section, allowing selective bus segmentation. In SN74LVC162244ADL-based designs, this enables software-defined isolation of memory banks, sensor clusters, or peripheral groups-reducing system-level contention and simplifying fault containment without additional logic gates.

Is SN74LVC162244ADL pin-compatible with earlier SN74LVC162244A variants?

Yes, SN74LVC162244ADL maintains full pin-to-pin compatibility with all SN74LVC162244A family members-including SN74LVC162244ADGGR and SN74LVC162244ADGVR-across all 48-pin packages (SSOP, TSSOP, TVSOP). The DL suffix denotes the SSOP variant, and TI confirms identical pin functions and ordering conventions in the Package Option Addendum.
