Product details
Overview
74LVCH162244APAG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit buffer/driver with 3-state outputs, 5V-tolerant I/O, bus-hold, and ±12mA drive capability. It supports mixed 3.3V/5V systems, operates from –40°C to +85°C, and delivers <500ps output skew at 3.3V for high-speed bus interfacing in industrial control backplanes.
For engineers reviewing the 74LVCH162244APAG datasheet, 74LVCH162244APAG pinout, 74LVCH162244APAG application, or 74LVCH162244APAG equivalent, key selection criteria include 5V-tolerant inputs/outputs, bus-hold functionality eliminating external pull resistors, TSSOP-48 package compatibility, and verified ±12mA drive strength under industrial temperature conditions.
Technical Context
The 74LVCH162244APAG implements four independent 4-bit non-inverting buffers, each with active-low 3-state enable (OE), symmetrical output drivers, and internal series termination to suppress line noise. All 32 I/O pins-including inputs, outputs, and OE-are 5V tolerant and feature bus-hold circuitry to retain last valid logic state during high-impedance transitions.
It operates across VCC = 2.7V–3.6V with static ICC ≤ 10μA, supports true 3.3V logic thresholds (VIH = 2.0V min, VIL = 0.8V max at VCC ≥ 2.7V), and guarantees tPLH/tPHL ≤ 4.4ns and tPZH/tPHZ ≤ 5.5ns at 3.3V, enabling reliable timing in synchronous bus applications up to 200MHz system clock domains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC162244ADGGR | Same 16-bit architecture, identical pinout, but TI version lacks bus-hold and internal series termination | Requires external pull resistors and may need external termination for high-speed traces | Select when cost sensitivity outweighs bus-hold convenience and board space is available for discrete support components |
| 74ALVC162244PW | NXP variant offers same 5V tolerance and ±24mA drive, but wider VCC range (1.65V–3.6V) and no bus-hold | Better suited for ultra-low-voltage operation but adds complexity in 3.3V-only designs due to higher drive overshoot risk | Prefer only if system requires sub-2.7V operation or needs stronger drive than ±12mA; otherwise, 74LVCH162244APAG provides optimal balance |
Compared with SN74LVC162244ADGGR and 74ALVC162244PW, the 74LVCH162244APAG uniquely integrates bus-hold and internal series termination-reducing BOM count by up to 32 passive components-and delivers tighter output skew (≤500ps vs. ≥700ps) critical for synchronized multi-signal routing.

FAQ
What is the maximum operating voltage for 74LVCH162244APAG I/O pins?
The 74LVCH162244APAG supports absolute maximum I/O terminal voltage of –0.5V to +6.5V relative to GND, with guaranteed 5V tolerance (0V to 5.5V) under normal operation. This allows safe connection to 5V peripherals while powered from a 3.3V supply, making it ideal for voltage translation in mixed-supply systems without external level shifters.
Does 74LVCH162244APAG require external pull-up or pull-down resistors?
No, the 74LVCH162244APAG includes integrated bus-hold circuitry on all data input pins (1A1–4A4), which actively retains the last valid logic state when inputs float. This eliminates the need for external pull resistors, reducing BOM count and PCB area-particularly valuable in space-constrained industrial modules and high-density telecom line cards.
What is the guaranteed output drive strength of 74LVCH162244APAG at 3.3V supply?
At VCC = 3.3V, the 74LVCH162244APAG guarantees ±12mA output drive strength into specified threshold levels (VOH ≥ 2.0V at IOH = –12mA; VOL ≤ 0.8V at IOL = 12mA). This enables direct driving of multiple LVTTL loads or lightly terminated transmission lines without external buffers, supporting robust signal integrity in noisy industrial environments.
How does the internal series termination in 74LVCH162244APAG improve signal integrity?
The 74LVCH162244APAG incorporates internal series resistors in its output structure, which dampen signal reflections on PCB traces and cables. This reduces ringing and EMI, especially under light-load conditions common in backplane and FFC interconnects-eliminating the need for discrete 22Ω–33Ω series resistors and simplifying layout for high-speed parallel buses up to 25MHz.
Is 74LVCH162244APAG compatible with standard TSSOP-48 footprints?
Yes, the 74LVCH162244APAG uses a standard JEDEC MO-153 compliant TSSOP-48 package (12.5mm × 6.1mm, 0.5mm pitch) with green molding compound. Its pinout matches industry-standard 16-bit buffer layouts, enabling drop-in replacement in existing designs using compatible TSSOP-48 logic devices-no PCB redesign required for mechanical or thermal integration.
