Product details
Overview
74LVCH162244ADGG,1 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 and features four independent output enables (1OE–4OE) for granular control of four 4-bit groups. Used in high-speed parallel bus interfaces requiring signal integrity and input state retention.
For engineers reviewing the 74LVCH162244ADGG,1 datasheet, 74LVCH162244ADGG,1 pinout, 74LVCH162244ADGG,1 application, or 74LVCH162244ADGG,1 equivalent, this device is selected for its combination of low-voltage operation, built-in termination, bus hold functionality, and partial power-down (IOFF) support in industrial and embedded bus buffering.
Technical Context
This device implements a multibyte flow-through architecture with Schmitt-trigger inputs for noise immunity and tolerance to slow edge rates. Each of the four 4-bit sections operates independently via dedicated active-low output enables (1OE–4OE), enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit buffers.
The IOFF circuit disables outputs during partial power-down to prevent backflow current, while bus hold eliminates external pull-ups on unused data inputs. Inputs tolerate up to 5.5 V regardless of VCC, supporting robust level translation across 1.2 V–3.6 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct interface with modern low-voltage logic while maintaining compatibility with legacy 3.3 V systems. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V signals without level shifters in mixed-voltage environments. |
| Propagation Delay (VCC = 3.3 V) | Typ. 2.7 ns - Supports high-speed parallel bus timing in applications up to ~300 MHz effective data rate. |
| Series Termination | 30 Ω per output - Reduces signal reflections on PCB traces, minimizing need for external termination components. |
| Bus Hold Current | ±75 μA at VCC = 3.0 V - Actively maintains logic state on floating inputs, eliminating external pull-up/pull-down resistors. |
| IOFF Leakage | ±20 μA max at VCC = 0 V - Prevents damaging back-current during hot-insertion or partial power-down sequences. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and under-hood automotive-adjacent applications. |
Pinout & Package
TSSOP48 (SOT362-1) package: 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, 1.2 mm max height. Designed for high-density PCB layouts with low inductance power/ground pin distribution.
| 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 Y0–Y3); HIGH forces high-impedance state for bus sharing. |
| 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 | All have bus hold; accept 1.2 V–3.6 V logic levels and tolerate up to 5.5 V. |
| 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 | Each includes 30 Ω series resistor; drive 50 Ω transmission lines directly with reduced ringing. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and supply noise across the 16-bit bus. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins ensure low-inductance return paths and suppress ground bounce in fast-switching operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Reduces PCB component count and layout complexity for impedance-matched parallel buses. |
| Bus hold on all data inputs | Eliminates need for external pull-up resistors on unused or unterminated inputs, saving board space and BOM cost. |
| IOFF partial power-down protection | Prevents back-current flow when VCC = 0 V but I/O pins remain biased, critical for hot-swap and power sequencing. |
| Schmitt-trigger inputs | Enables reliable operation with slow-rising/falling signals (e.g., from mechanical switches or long traces) without added hysteresis circuitry. |
| JEDEC-compliant voltage ranges | Meets JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) standards for interoperability. |
Applications
| Industrial PLC Backplane Interface | Embedded Memory Expansion Bus |

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 |
|---|---|---|---|
| 74LVC162244ADGG | No bus hold; otherwise identical pinout, electrical specs, and package. | Requires external pull-ups on unused inputs; unsuitable where floating inputs must be actively held. | Select when bus hold is unnecessary and lowest possible static current is prioritized. |
| SN74LVC162244ADGGR | Texas Instruments part; same function but different IOFF behavior and slightly higher max tpd (8.5 ns vs 7.5 ns @ +125 °C). | Not qualified to −40 °C to +125 °C over full voltage range; JEDEC compliance differs. | Choose only if TI supply chain alignment is required and thermal derating margins permit. |
Compared with 74LVC162244ADGG and SN74LVC162244ADGGR, the 74LVCH162244ADGG,1 uniquely combines bus hold, full −40 °C to +125 °C operation across 1.2–3.6 V, and tighter disable timing-making it optimal for ruggedized, maintenance-free industrial bus interfaces.

FAQ
Does 74LVCH162244ADGG,1 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, preventing back-current flow from live I/O lines into the unpowered device. This enables safe insertion/removal in powered-backplane systems, provided input voltages stay within the 5.5 V absolute maximum rating.
Can bus hold be disabled on 74LVCH162244ADGG,1?
No. Bus hold is permanently enabled on all data inputs (1A0–4A3) and cannot be disabled via control pins or configuration. It activates automatically when inputs float, drawing ±75 μA at VCC = 3.0 V to maintain the last valid logic state.
What is the impact of the 30 Ω series termination on signal rise time?
The 30 Ω resistor, combined with typical PCB trace impedance (~50 Ω), forms a source-series termination that reduces edge overshoot and ringing without significantly degrading rise time-measured tPLH/tPHL remains ≤7.5 ns at VCC = 3.6 V and +125 °C, preserving timing margins.
How does 74LVCH162244ADGG,1 differ from standard 74LVC162244A in system-level design?
Unlike the base LVC version, the LVCH variant adds bus hold (removing external pull-ups), retains full 5.5 V input tolerance, and maintains identical timing and drive strength-enabling simpler, more robust designs in environments with unterminated or intermittently connected buses.
