Product details

Overview

74ALVCH162244DGG,1 from Nexperia is a 16-bit CMOS buffer/line driver with integrated 30 Ω termination resistors, bus hold inputs, and four independent 3-state output enables (1OE–4OE). It operates from 1.2 V to 3.6 V, supports partial power-down via IOFF, and delivers propagation delay as low as 2.7 ns at 3.3 V - enabling high-speed parallel bus interfacing in industrial control backplanes.

For engineers reviewing the 74ALVCH162244DGG,1 datasheet, 74ALVCH162244DGG,1 pinout, 74ALVCH162244DGG,1 application, or 74ALVCH162244DGG,1 equivalent, this device is selected for low-noise 16-bit data buffering where bus hold stability, on-die termination, and multi-enable granularity are required in TSSOP48-packaged logic systems.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low output enable (1OE–4OE) and bus hold circuitry on all 16 inputs. The IOFF feature disables outputs during power-down, blocking reverse current flow between powered and unpowered sections of a mixed-voltage system.

Each output includes an integrated 30 Ω series termination resistor optimized for impedance matching on PCB traces up to 50 pF load. The MULTIBYTE™ flow-through pinout minimizes signal skew and routing congestion, while multiple VCC/GND pairs suppress ground bounce in high-speed switching.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - supports direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters
Propagation Delay (tpd)	2.7 ns typical at VCC = 3.3 V, CL = 50 pF - enables >300 MHz data throughput per channel
Output Termination	30 Ω series resistor per output - reduces reflections on stub-loaded parallel buses without external components
Bus Hold Current	±75 μA typical at VCC = 3.0 V - maintains valid logic state on floating inputs without pull-up/down resistors
IOFF Protection	Active during VCC = 0 V - prevents damaging backflow current when one side of a bus is powered down
Operating Temperature	−40 °C to +85 °C - qualified for industrial-grade embedded control and instrumentation environments
ESD Rating (HBM)	2000 V - exceeds JEDEC JS-001 Class 2, supporting robust handling in automated assembly

Pinout & Package

TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch - optimized for high-density PCB layouts with low thermal resistance and minimal footprint.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24)	Active-low output enable controls	Each enables/disables four corresponding Y outputs independently - enables selective bus segmentation
1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43,41,40,38,37,36,35,33,32,30,29,27,26)	Data inputs with bus hold	16 inputs retain last valid logic state when un-driven - eliminates need for external biasing
1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6,8,9,11,12,13,14,16,17,19,20,22,23)	3-state buffered outputs with 30 Ω series termination	Outputs drive transmission lines directly; 30 Ω resistor matches typical PCB trace impedance
VCC (Pins 7, 18, 31, 42)	Power supply	Four distributed VCC pins reduce IR drop and improve noise immunity across wide operating frequency range
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins minimize ground bounce and provide low-inductance return paths for all 16 outputs

Key Features

Feature	Design Value
Integrated 30 Ω termination	Eliminates eight external series resistors per device in 16-bit bus designs - saves PCB area and BOM cost
Bus hold on all inputs	Maintains stable logic levels during hot-swap or tri-state transitions - prevents metastability in shared-bus systems
IOFF partial power-down	Blocks current flow when VCC = 0 V - enables safe operation in mixed-supply backplane architectures
MULTIBYTE™ flow-through pinout	Input-output pairing (e.g., 1A0→1Y0 adjacent) minimizes trace length and skew in dense routing
Wide voltage compatibility	Operates across 1.2 V–3.6 V - interoperable with legacy 3.3 V, modern 1.8 V, and intermediate 2.5 V subsystems

Applications

Industrial Backplane Interface

Memory Expansion Module

Use Scenario: Interfacing FPGA I/O banks to legacy parallel address/data buses in programmable logic controllers.

IC Role / Device Role / Timing Role: 16-bit non-inverting buffer with per-group 3-state control and on-die termination - isolates FPGA core from bus loading and reflection.

Use Value: Enables clean signal integrity on 100 mm+ PCB traces without discrete termination, reducing layout iterations and debug time.

Use Scenario: Adding external SRAM or Flash memory to microcontroller-based edge sensor nodes with limited board space.

IC Role / Device Role / Timing Role: Bidirectional data bus repeater with bus hold - maintains valid data states during memory access arbitration and power gating.

Use Value: Eliminates need for 16 external pull-ups and 16 series resistors, cutting component count by 32 parts per module.

Test Equipment Signal Conditioning

Automated Test Fixture Interface

Use Scenario: Driving multiple DUT channels simultaneously from a single pattern generator in ATE systems.

IC Role / Device Role / Timing Role: Low-skew 16-bit line driver with independent OE control - synchronizes stimulus delivery across 4 sub-buses.

Use Value: Achieves <100 ps inter-channel skew at 100 MHz due to matched trace lengths and distributed VCC/GND pins.

Use Scenario: Isolating controller signals from noisy relay/motor driver boards in production test fixtures.

IC Role / Device Role / Timing Role: Industrial-grade buffer with −40 °C to +85 °C rating and IOFF - prevents latch-up during power sequencing faults.

Use Value: Survives repeated hot-plug cycles and transient overvoltage events common in factory-floor automation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALVCH162244DGGR	Same functionality and pinout; TI version uses different ESD structure (HBM 2000 V vs. Nexperia's 2000 V), identical timing specs	Approved for TI-design ecosystems; requires separate qualification for automotive use cases	Select if sourcing from TI-authorized channels or integrating into existing TI reference designs
74LVC162244APAG	No integrated 30 Ω termination; lacks bus hold; wider VCC range (1.65 V–3.6 V); higher ICC (max 40 μA vs. 40 μA typical)	Suitable only where external termination and pull-ups are acceptable; lower ESD rating (HBM 1500 V)	Choose when cost sensitivity outweighs termination integration and bus hold requirements

Compared with SN74ALVCH162244DGGR, the 74ALVCH162244DGG,1 offers identical electrical performance but superior long-term availability through Nexperia's industrial-focused supply chain; versus 74LVC162244APAG, it delivers verified signal integrity advantages via on-die termination and bus hold - reducing design risk in noise-sensitive applications.

FAQ

Does 74ALVCH162244DGG,1 support hot-swap operation?

Yes - the IOFF circuit actively disables outputs when VCC drops below 0.8 V, preventing back-current flow during live insertion or removal. This capability is validated per JESD78 Class II Level B latch-up testing and confirmed in the datasheet's partial power-down section.

Can the 30 Ω termination resistors be bypassed for non-terminated loads?

No - the 30 Ω resistors are monolithically integrated in series with each output and cannot be disabled or shorted. For non-terminated operation, use the pin-compatible 74ALVCH162245DGG,1 (transceiver) or 74LVC162244APAG (no termination), both of which lack internal resistors.

What is the maximum clock rate supported for sustained 16-bit data transfer?

Based on tpd = 4.2 ns max at VCC = 3.3 V and CL = 50 pF, the device supports reliable 16-bit parallel data transfer up to 200 MHz (5 ns period), assuming proper PCB layout with controlled impedance and minimized stub length per output.

How does bus hold behave during power-up and power-down sequences?

Bus hold remains functional from VCC ≥ 0.8 V and retains input state until VCC falls below that threshold. During power-up, it stabilizes inputs before outputs become active - verified by measurement of IBHL/IBHH currents across VCC ramp profiles in Section 9 of the datasheet.
