Product details

Overview

74LVCH162244ADGG from Nexperia is a 16-bit CMOS buffer/line driver with integrated 30 Ω series termination resistors, 3-state outputs, bus hold on all data inputs, and 5 V tolerant I/O operating from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V systems, features four independent output enables (1OE–4OE), and is rated for operation from −40 °C to +125 °C in TSSOP48 package.

For engineers reviewing the 74LVCH162244ADGG datasheet, 74LVCH162244ADGG pinout, 74LVCH162244ADGG application, or 74LVCH162244ADGG equivalent, this device is selected for high-speed parallel bus buffering with built-in termination and robust partial-power-down (IOFF) protection in industrial control backplanes and memory interface subsystems.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each controlled by its own active-low output enable (1OE–4OE). Each buffer channel includes Schmitt-trigger inputs for noise immunity and bus-hold circuitry on all data inputs-eliminating external pull-ups for unused pins.

The integrated 30 Ω series termination resistors are placed on all 16 output lines (1Y0–4Y3), enabling impedance-matched signal routing on PCB traces without discrete resistors. IOFF functionality disables outputs and blocks backflow current during partial power-down, meeting JEDEC JESD78 requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - Enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains
I/O Voltage Tolerance	Up to 5.5 V - Allows safe connection to 5 V buses without level shifters
Propagation Delay (t_pd)	Max 7.5 ns at V_CC = 3.3 V, T_A = +125 °C - Supports >100 MHz bus clocking with timing margin
Output Termination	30 Ω series resistor per output - Reduces signal reflections on stub-loaded parallel buses
Bus Hold Current	±60 μA to ±75 μA (V_CC = 3.0 V) - Maintains stable logic state on floating inputs without external components
IOFF Leakage	Max ±20 μA at V_CC = 0 V, V_I/O = 5.5 V - Prevents damaging backfeed current during hot-swap or partial power-down
ESD Rating (HBM)	>2000 V - Meets ANSI/ESDA/JEDEC JS-001 Class 2 for board-level handling robustness

Pinout & Package

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24)	Active-low output enable	Each controls 4 outputs (e.g., 1OE enables 1Y0–1Y3); HIGH forces high-impedance state
1A0–4A3 (Pins 47,46,44,43,41,40,38,37,36,35,33,32,30,29,27,26)	Data input	All 16 inputs feature bus hold; tolerate 0 V to 5.5 V regardless of V_CC
1Y0–4Y3 (Pins 2,3,5,6,8,9,11,12,13,14,16,17,19,20,22,23)	Data output	Each includes integrated 30 Ω series termination; 3-state capable
V_CC (Pins 7,18,31,42)	Power supply	Four dedicated supply pins minimize IR drop and ground bounce across 16-bit bus
GND (Pins 4,10,15,21,28,34,39,45)	Ground reference	Eight ground pins provide low-inductance return paths for switching currents

Key Features

Feature	Design Value
Integrated 30 Ω series termination	Eliminates 16 discrete SMT resistors on PCB, reducing BOM count and layout area
Bus hold on all data inputs	Removes need for external pull-up/pull-down resistors on unused or unterminated inputs
5 V tolerant I/O at any V_CC (1.2–3.6 V)	Enables seamless voltage translation in mixed-supply systems without external translators
IOFF partial power-down protection	Prevents current backflow when V_CC = 0 V but I/O pins remain biased to 5 V
Schmitt-trigger inputs	Accept slow-rising/falling signals (Δt/ΔV up to 20 ns/V at 1.2 V) without oscillation

Applications

Industrial Backplane Buffering

Memory Interface Expansion

Use Scenario: Isolating and driving 16-bit address/data buses across modular PLC I/O racks with long trace lengths.

IC Role / Device Role / Timing Role: Non-inverting buffer with on-die termination ensures clean edge integrity and reduces stub reflections on multi-drop backplanes.

Use Value: Eliminates external termination network, cuts layout complexity, and maintains timing margin under −40 °C to +125 °C thermal cycling.

Use Scenario: Extending SRAM or Flash memory data/address bus to secondary controller in embedded instrumentation.

IC Role / Device Role / Timing Role: Bidirectional bus repeater with 3-state control enables time-multiplexed access between two masters sharing one memory device.

Use Value: Bus hold prevents floating states during arbitration gaps; 5 V tolerance allows legacy memory devices to coexist with 3.3 V controllers.

Automated Test Equipment (ATE) Signal Conditioning

Programmable Logic Interface

Use Scenario: Driving high-capacitance fixture cables from FPGA I/O banks in boundary-scan test systems.

IC Role / Device Role / Timing Role: Output driver with programmable enable per 4-bit group synchronizes signal launch to test pattern timing windows.

Use Value: Integrated 30 Ω resistors match typical 50 Ω cable impedance, suppressing ringing and overshoot at 100+ MHz toggle rates.

Use Scenario: Interfacing CPLD configuration data lines to microcontroller GPIO headers in field-upgradable modules.

IC Role / Device Role / Timing Role: Level-shifting buffer translates 1.8 V CPLD I/O to 3.3 V MCU side while holding idle states during reconfiguration.

Use Value: Eliminates discrete level shifters and pull-ups; IOFF protects CPLD during MCU firmware update cycles where V_CC may be interrupted.

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
SN74LVC162244ADGGR	No bus hold; IOFF supported; same 30 Ω termination and 5 V tolerance	Lacks bus hold-requires external pull resistors on unused inputs	Select when cost sensitivity outweighs need for bus hold and system-level I/O pin count is fully utilized
74LVCH162244ADGV	Identical electrical specs; TVSOP48 package (4.4 mm width, 0.4 mm pitch)	Higher pin density; requires finer-pitch PCB assembly capability	Select for space-constrained designs where footprint reduction justifies tighter layout tolerances and rework complexity

Compared with SN74LVC162244ADGGR, the 74LVCH162244ADGG adds bus hold to reduce external components; compared with 74LVCH162244ADGV, it trades smaller footprint for easier manufacturability in TSSOP48's 0.5 mm pitch.

FAQ

Does 74LVCH162244ADGG support hot-swap insertion?

Yes-it features IOFF circuitry that disables outputs and blocks backflow current when V_CC = 0 V while I/O pins remain at up to 5.5 V, satisfying JEDEC JESD78 requirements for partial power-down robustness during live insertion into powered backplanes.

Can bus hold be disabled on 74LVCH162244ADGG?

No-bus hold is permanently enabled on all data inputs (1A0–4A3) and cannot be disabled via control pin or voltage. It activates automatically when input voltage is within 0.2 V of GND or V_CC, providing ±60–75 μA sustaining current to maintain logic state.

What is the maximum capacitive load this device can drive reliably?

Per Nexperia's dynamic characterization, the device maintains specified t_pd, t_en, and t_dis up to 50 pF load capacitance at V_CC ≥ 2.7 V. Driving >50 pF may increase propagation delay and reduce noise margin but does not damage the part.

How does the 30 Ω series termination interact with PCB trace impedance?

The 30 Ω resistor is intended for use with 50–60 Ω single-ended PCB traces. When placed at the source (driver end), it forms a series match with trace Z₀, minimizing reflections for point-to-point or short-stub topologies-no external termination resistor is required at the receiver end.
