Product details
Overview
74LVC162244ADGG from Nexperia is a 16-bit 3-state buffer/line driver with integrated 30 Ω series termination resistors, 5 V-tolerant I/O, and four independent output-enable inputs (1OE–4OE). It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features Schmitt-trigger inputs for noise immunity. It is used in high-speed parallel bus interfaces requiring controlled impedance and low ground bounce.
For engineers reviewing the 74LVC162244ADGG datasheet, 74LVC162244ADGG pinout, 74LVC162244ADGG application, or 74LVC162244ADGG equivalent, key selection criteria include its 30 Ω on-die series termination, IOFF partial power-down capability, bus-hold-free operation (vs. LVCH variant), TSSOP48 package with 48 pins, and guaranteed −40 °C to +125 °C operation.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low output enable (1OE–4OE) controlling four outputs. All inputs feature Schmitt-trigger action to tolerate slow-rising signals, and the IOFF circuit ensures zero backflow current during partial power-down.
It delivers rail-to-rail CMOS-compatible output swing, supports direct TTL-level interfacing, and integrates low-inductance multiple VCC/GND pins to minimize switching noise and ground bounce in dense PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH162244ADGG | Includes bus-hold on all data inputs; same pinout, package, and electrical specs otherwise | Eliminates need for external pull-ups on unused inputs; increases input leakage slightly | Select when floating inputs must be actively held without external components |
| SN74LVC162244ADGGR | Texas Instruments variant; identical function, 30 Ω termination, and 5 V tolerance; minor timing spec variances (<0.3 ns) | Same TSSOP48 footprint; TI's qualification flow differs (AEC-Q100 not claimed) | Select when TI supply chain alignment or dual-sourcing is required |
Compared with 74LVCH162244ADGG, this part omits bus-hold to reduce input leakage and static power; compared with SN74LVC162244ADGGR, it offers Nexperia's extended temperature rating (−40 °C to +125 °C) and higher HBM ESD rating (2000 V vs. 1500 V).

FAQ
What is the maximum clock frequency supported by the 74LVC162244ADGG?
The device does not specify a maximum clock frequency directly, but its propagation delay (tpd) is 1.0–7.5 ns at VCC = 3.0–3.6 V, supporting reliable operation up to ~100 MHz in well-terminated parallel bus applications. System-level timing depends on trace length, load capacitance, and termination matching.
Can the 74LVC162244ADGG drive 50 Ω transmission lines directly?
No - its integrated 30 Ω series resistor is designed for source termination into typical PCB trace impedances (60–75 Ω), not 50 Ω coaxial lines. For 50 Ω systems, an external series resistor (20 Ω) should be added to achieve proper source termination.
Does the 74LVC162244ADGG support hot insertion?
Yes - the IOFF circuit actively disables outputs and limits backflow current to ±10 μA when VCC = 0 V, enabling safe hot-plug operation in modular backplane systems without risk of damage to powered subsystems.
How does the Schmitt-trigger input improve system reliability?
Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V), rejecting noise and slow-rising signals that could cause metastability or double-clocking in downstream logic. This is especially valuable for interfacing with mechanical switches, long cables, or optocouplers in industrial control environments.
