Nexperia USA Inc. 74LVC162244ADGVJ

Overview

74LVC162244ADGV from Nexperia is a 16-bit 3-state buffer/line driver with integrated 30 Ω series termination resistors, 5 V-tolerant I/O, and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V systems, features Schmitt-trigger inputs for noise immunity, and includes IOFF circuitry for partial power-down protection. It is used in high-speed parallel bus interfaces such as memory expansion, FPGA I/O bridging, and industrial control backplanes.

For engineers reviewing the 74LVC162244ADGV datasheet, 74LVC162244ADGV pinout, 74LVC162244ADGV application, or 74LVC162244ADGV equivalent, key selection criteria include its 30 Ω on-die termination for signal integrity, -40 °C to +125 °C temperature rating, TVSOP48 (SOT480-1) package with 0.4 mm pitch, and bus-hold-free operation (distinct from LVCH variant).

Technical Context

This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Its architecture enables flexible partitioning-configurable as one 16-bit, two 8-bit, or four 4-bit drivers-without external logic. The IOFF circuit ensures outputs enter high-impedance state during power-down, blocking backflow current.

Schmitt-trigger inputs provide hysteresis (typ. 0.2 V at VCC = 3.3 V), enabling robust operation with slow-rising signals. The 30 Ω series resistors are placed on all 16 Y-output pins, reducing reflections on transmission lines without requiring discrete termination components.

Key Specifications

FAQ

Is 74LVC162244ADGV pin-compatible with 74LVCH162244ADGV?

Yes - both share identical TVSOP48 (SOT480-1) pinout, electrical timing, and 30 Ω termination. The only functional difference is that the LVCH variant includes bus-hold circuitry on data inputs, while the LVC variant does not. No PCB redesign is needed for substitution, but unused inputs on the LVC version require external pull-up/pull-down if not driven.

What is the maximum clock frequency supported by this buffer in a 16-bit bus application?

Based on worst-case propagation delay of 7.5 ns at VCC = 3.3 V and -40 °C to +125 °C, the device supports reliable operation up to approximately 133 MHz for single-cycle data transfer (1/7.5 ns). For setup/hold timing-critical protocols like SRAM access, derating to ≤80 MHz is recommended to accommodate trace skew and load variation.

Does this device support hot-swap or live-insertion in powered backplanes?

Yes - the IOFF circuit ensures outputs go high-impedance when VCC = 0 V, preventing back-current flow even if inputs are driven at 5.5 V. This allows safe insertion into live backplanes, provided that VCC ramp-up sequencing does not violate absolute maximum ratings (e.g., VI applied before VCC).

Can the 30 Ω series resistors be bypassed for non-terminated use cases?

No - the 30 Ω resistors are monolithically integrated in series with each Y-output and cannot be disabled or shorted. If termination is unwanted, select the non-terminated SN74LVC16244ADGGR instead. The 74LVC162244ADGV is purpose-built for impedance-controlled environments where reflection suppression is required.
