Nexperia USA Inc. 74ALVC162836ADGG,1

Overview

74ALVC162836ADGG,1 from Nexperia is a 20-bit registered bus driver with inverted latch enable (active LOW), 3-state outputs, and integrated 30 Ω series termination resistors on all outputs. It operates from 1.2 V to 3.6 V, supports transparent/latched data flow via LE and edge-triggered CP, and delivers ±12 mA drive at 3.0 V. It is used in high-speed parallel bus interfaces requiring impedance-matched signal integrity, such as memory expansion or FPGA I/O bridging.

For engineers reviewing the 74ALVC162836ADGG,1 datasheet, 74ALVC162836ADGG,1 pinout, 74ALVC162836ADGG,1 application, or 74ALVC162836ADGG,1 equivalent, key selection criteria include its 30 Ω on-die termination, TSSOP56 package with multiground/voltage pins for noise suppression, 2.8 ns typical propagation delay at 3.3 V, and compatibility with TTL-level inputs across its full supply range.

Technical Context

This device implements a dual-control register architecture: LE (latch enable, active LOW) determines transparency vs. latching mode, while CP (clock input, LOW-to-HIGH edge-triggered) captures A-input data into internal flip-flops. Output enable (OE, active LOW) independently controls 3-state output drivers without affecting latch state.

Each output includes 30 Ω series resistors in both HIGH and LOW states, enabling direct termination for 50 Ω transmission lines at 85 °C. The design incorporates diode clamps on all inputs to VCC and GND, low-inductance multiple VCC/GND pins, and compliance with JEDEC JESD8-5 and JESD8B/JESD36 standards for 2.3–3.6 V operation.

FAQ

What is the purpose of the inverted latch enable (LE) input?

The LE input is active LOW: when LE is LOW, the device operates in transparent mode, passing A-inputs directly to Y-outputs; when LE is HIGH, the device enters latched mode and captures A-input data on the LOW-to-HIGH transition of CP. This inversion simplifies control logic in systems where latching is the default state, reducing external gate count.

Can the 74ALVC162836ADGG,1 drive 50 Ω transmission lines without external resistors?

Yes - each output integrates a matched 30 Ω series resistor in both HIGH and LOW states. When combined with typical PCB trace impedance (≈20 Ω), this achieves near-perfect 50 Ω source termination, eliminating ringing and reflections on controlled-impedance lines up to 85 °C, as verified in Nexperia's characterization data.

How should OE be handled during power-up to ensure safe 3-state behavior?

OE must be tied to VCC through a pull-up resistor during power-up and power-down. The minimum resistor value depends on the current-sinking capability of the driving logic, but a 10 kΩ resistor is commonly used. This guarantees outputs remain in high-impedance until valid control signals are established, preventing bus contention.

Does the device support hot insertion or live swapping in backplane applications?

No - the 74ALVC162836ADGG,1 is not hot-swap rated. Its absolute maximum ratings do not include powered-insertion stress conditions, and the lack of Ioff (power-off protection) means outputs may source/sink current when VCC is absent. For hot-swap applications, additional protection circuitry or a hot-swap controller is required.
