Product details

Overview

SN74LVC162244AGRDR 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 clock distribution in industrial motor drives and network switches.

For engineers reviewing the SN74LVC162244AGRDR datasheet, SN74LVC162244AGRDR pinout, SN74LVC162244AGRDR application, or SN74LVC162244AGRDR equivalent, key selection criteria include its 3.6-V max supply, 4.4-ns propagation delay at 3.3 V, I_off support for live insertion, and compatibility with TSSOP-48 packaging for high-density PCB layouts.

Technical Context

This device implements four independent 4-bit noninverting buffer sections, each with dedicated active-low OE control (1OE–4OE), enabling selective isolation of A→Y signal paths. Its CMOS design supports true 3-state outputs with symmetrical drive strength (±12 mA at 3.3 V) and built-in series termination to suppress overshoot/undershoot without external resistors.

The SN74LVC162244AGRDR operates across 1.65–3.6 V while accepting input voltages up to 5.5 V on all pins-making it suitable for voltage translation between 3.3-V logic and legacy 5-V systems. Its I_off circuitry prevents back-drive current when V_CC = 0 V, satisfying partial-power-down requirements in hot-swap applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 3.6 V - Enables operation across low-voltage embedded systems and standard 3.3-V rails.
t_pd (Max)	4.4 ns at V_CC = 3.3 V - Supports high-speed data transfer in memory and bus applications up to ~227 MHz.
I_OL/I_OH	±12 mA at V_CC = 3.3 V - Drives moderate capacitive loads (e.g., 10–15 pF traces) without external buffers.
Input Voltage Tolerance	Up to 5.5 V - Allows direct interfacing with 5-V microcontrollers or legacy peripherals without level shifters.
Output Series Resistance	26 Ω (equivalent) - Reduces signal ringing and EMI on PCB traces; eliminates need for discrete series resistors.
I_off	±10 µA at V_CC = 0 V - Enables safe live insertion and back-drive protection during power sequencing.
ESD Rating	2000-V HBM, 1000-V CDM - Meets industrial-grade robustness requirements for manufacturing and field operation.

Pinout & Package

TSSOP-48 package (DGG drawing), body size 12.50 × 6.10 mm, 0.5-mm pitch, RoHS-compliant green finish (CU NIPDAU), MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1OE–4OE	Active-low output enable (4×)	Individually disables corresponding 4-bit Y-output group; tied high via pullup for default high-Z during power-up.
1A1–4A4	Noninverting input (16×)	Accepts 5.5-V-tolerant logic signals; no clamping diodes required for mixed-voltage interfacing.
1Y1–4Y4	Noninverting 3-state output (16×)	Drives bidirectional buses with controlled edge rates; internal 26-Ω series resistance minimizes reflections.
V_CC (Pins 7, 18, 31, 42)	Power supply (4×)	Multiple V_CC pins reduce IR drop and improve noise immunity; each requires local 0.01–0.1-µF bypass capacitor.
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference (8×)	High-pin-count ground array lowers ground bounce (V_OLP < 0.8 V at 3.3 V) and improves signal integrity.

Key Features

Feature	Design Value
Mixed-mode signal operation	5.5-V-tolerant inputs allow seamless interface between 3.3-V logic and 5-V peripherals without external translators.
Integrated 26-Ω series output resistors	Eliminates need for 16 discrete series resistors, reducing BOM count and PCB area in high-pin-count bus drivers.
I_off partial-power-down support	Prevents damaging current flow when V_CC is unpowered-critical for hot-plug modules and modular backplanes.
Low ground/power bounce	Typical V_OLP < 0.8 V and V_OHV > 2 V at 3.3 V ensures clean switching margins in noise-sensitive applications.
Widebus™ architecture	Optimized pinout and layout for dense memory and address bus routing, minimizing trace crosstalk and stub length.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16244ADGGR	Same pinout, identical electrical specs, but lacks I_off and 5.5-V input tolerance; rated only to V_CC + 0.5 V.	Not suitable for hot-swap or mixed-voltage systems where inputs may be driven before V_CC is stable.	Select SN74LVC162244AGRDR when I_off or 5-V input compatibility is required; SN74LVC16244ADGGR suffices for single-rail 3.3-V-only designs.
74ALVC162244PW	Same function and pinout; higher drive (±24 mA), faster t_pd (3.2 ns), but narrower V_CC range (1.65–2.7 V) and no 5.5-V input tolerance.	Restricted to low-voltage battery-powered systems; incompatible with 3.3-V supplies above 2.7 V or 5-V interfaces.	Choose 74ALVC162244PW only for ultra-low-voltage, high-speed applications below 2.7 V; SN74LVC162244AGRDR provides broader supply and interface flexibility.

Compared with SN74LVC16244ADGGR and 74ALVC162244PW, the SN74LVC162244AGRDR uniquely combines 5.5-V input tolerance, I_off, and full 1.65–3.6-V operation-making it the only option among the three for robust mixed-voltage hot-swap systems.

FAQ

What is the maximum operating voltage for SN74LVC162244AGRDR inputs?

The SN74LVC162244AGRDR inputs tolerate up to 5.5 V regardless of V_CC level-enabling direct connection to 5-V logic sources even when powered from 1.65–3.6 V. This eliminates external level-shifting components in mixed-voltage designs and is confirmed in Section 7.3 (Recommended Operating Conditions) and Feature Description of the datasheet.

Does SN74LVC162244AGRDR support hot-plug insertion?

Yes, SN74LVC162244AGRDR supports hot-plug insertion via its I_off feature, which disables outputs and limits input/output leakage to ±10 µA when V_CC = 0 V. This prevents back-drive current and protects upstream logic-verified in Section 7.5 (Electrical Characteristics) and Detailed Description 9.3.

What is the purpose of the 26-Ω series resistance in SN74LVC162244AGRDR outputs?

The SN74LVC162244AGRDR integrates equivalent 26-Ω series resistors on all 16 outputs to damp signal reflections and reduce overshoot/undershoot-measured as typical V_OHV > 2 V and V_OLP < 0.8 V at 3.3 V. This eliminates the need for 16 discrete external resistors in high-speed bus designs.

How many independent output-enable controls does SN74LVC162244AGRDR provide?

SN74LVC162244AGRDR provides four independent active-low output-enable inputs (1OE, 2OE, 3OE, 4OE), each controlling a separate 4-bit output group (1Y1–1Y4, etc.). This enables granular bus segmentation and dynamic path isolation without affecting other channels-detailed in Pin Functions and Function Table sections.

Which package type corresponds to the SN74LVC162244AGRDR orderable part number?

SN74LVC162244AGRDR uses the TSSOP-48 package (drawing DGG), measuring 12.50 × 6.10 mm with 0.5-mm lead pitch. This is confirmed in the Orderable Addendum and Mechanical Data sections, where "R-PDSO-G48" and "TSSOP" are explicitly assigned to the GRDR suffix.
