Nexperia USA Inc. 74ALVC162836ADGG:1

Overview

74ALVC162836ADGG from Nexperia is a 20-bit registered bus driver with integrated 30 Ω series termination resistors, active-low latch enable (LE), active-low output enable (OE), and edge-triggered clock (CP). It operates across 1.2 V to 3.6 V supply, delivers ±12 mA drive at 3.0 V, and supports transparent/latched data flow for high-speed parallel bus interfacing in memory expansion and FPGA I/O buffering applications.

For engineers reviewing the 74ALVC162836ADGG datasheet, 74ALVC162836ADGG pinout, 74ALVC162836ADGG application, or 74ALVC162836ADGG equivalent, key selection criteria include its 30 Ω on-die termination, TSSOP56 package with multiground/voltage pins for noise suppression, guaranteed 240 MHz max clock frequency at 3.3 V, and JEDEC-compliant 1.2–3.6 V operation with TTL-level compatibility.

Technical Context

This device implements a dual-mode 20-bit register: when LE is HIGH, it operates in transparent mode; on the LOW-to-HIGH CP edge with LE HIGH, it latches A-inputs to Y-outputs. OE independently controls 3-state output enable without affecting internal latch state.

The integrated 30 Ω series resistors are placed in both HIGH and LOW output paths, enabling direct impedance matching to 50 Ω transmission lines at 85 °C - eliminating external termination components while maintaining signal integrity in high-speed parallel buses.

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 (A-to-Y pass-through); when LE is HIGH, it enables latching on the rising edge of CP. This inversion simplifies control logic in systems where latch activation is asserted by default-active signals, reducing external gate count and improving timing predictability.

Can the 74ALVC162836ADGG drive 50 Ω transmission lines directly?

Yes - each output integrates a 30 Ω series resistor optimized to match 50 Ω lines when combined with typical PCB trace impedance and load capacitance. At 85 °C, the device maintains this capability per datasheet specification, enabling clean edge rates and reduced reflections without external components.

How should OE be handled during power-up to ensure high-impedance outputs?

OE must be tied to VCC through a pullup resistor during power-up and power-down. The minimum resistor value depends on the driver's current-sinking capability; Nexperia recommends ≥10 kΩ for most applications. This ensures outputs remain in high-Z state until system firmware asserts valid OE control, preventing bus contention.

Does the device support mixed-voltage operation between inputs and outputs?

No - the 74ALVC162836ADGG is a single-supply device: all inputs and outputs reference the same VCC (1.2–3.6 V). Input thresholds scale with VCC, and outputs swing rail-to-rail. For true mixed-voltage translation, a dedicated level shifter (e.g., TXB0108) must be used upstream or downstream.
