Nexperia USA Inc. 74ALVC16836ADGG,11

Overview

74ALVC16836ADGG,11 from Nexperia is a 20-bit registered bus driver with inverted latch enable (LE), active-low 3-state output enable (OE), and edge-triggered clock (CP). It provides transparent or registered A-to-Y data flow in 1.2 V–3.6 V systems, delivers ±24 mA drive at 3.0 V, and supports high-speed operation up to 300 MHz at 3.3 V. It is used in high-density memory address/data buffering and synchronous bus interface applications.

For engineers reviewing the 74ALVC16836ADGG,11 datasheet, 74ALVC16836ADGG,11 pinout, 74ALVC16836ADGG,11 application, or 74ALVC16836ADGG,11 equivalent, key selection criteria include its dual-mode (transparent/latched) operation, TSSOP56 pin-compatible layout for multibyte flow-through routing, JEDEC-compliant voltage thresholds, and robust ESD protection (HBM >2000 V, CDM >1000 V).

Technical Context

This device implements a 20-bit register with independent control of latch enable (active LOW), clock (LOW-to-HIGH edge-triggered), and output enable (active LOW). Its register function latches input data on the rising edge of CP when LE is HIGH; when LE is LOW, it operates transparently. OE controls 3-state outputs without affecting internal latch state.

The IC uses advanced ALVC CMOS technology enabling wide VCC operation (1.2–3.6 V), TTL-level compatibility, and low-noise performance via multiple VCC/GND pins. Propagation delays range from 1.0 ns (VCC = 3.3 V, An→Yn) to 4.5 ns (LE→Yn), with setup/hold times as low as 0.3 ns for data-to-clock timing.

FAQ

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

The LE input is active LOW: when LE = LOW, the device operates in transparent mode (A-to-Y path enabled); when LE = HIGH, data is latched on the rising edge of CP. This inversion simplifies control logic in systems where latch activation is asserted by default-active signals, reducing need for external inverters in synchronous bus architectures.

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

OE must be held HIGH (inactive) during power-up to prevent bus contention. Tie OE to VCC via a pull-up resistor; minimum value depends on driver's current-sinking capability - typically 10 kΩ suffices for most applications, ensuring fast, glitch-free transition to high-Z before VCC stabilizes.

Does this device support hot-swap or live-insertion scenarios?

Yes - built-in input clamping diodes and ±50 mA absolute maximum clamping current (per IOK) allow safe exposure to overvoltage transients during insertion. However, OE must be asserted HIGH before power application, and VCC ramp rate must comply with recommended dV/dt limits (<1 V/ms) to avoid latch-up.

Can the 74ALVC16836ADGG,11 drive unterminated 50 Ω PCB traces directly?

Yes - its ±24 mA output drive at 3.0 V meets the requirement for driving 50 Ω transmission lines at 85°C, as confirmed in Section 2 ("Features and benefits"). This eliminates need for external series termination resistors in point-to-point or short-drop bus configurations, reducing component count and signal distortion.
