Nexperia USA Inc. 74ALVC16245DGG,112

Overview

74ALVC16245DGG,112 from Nexperia is a 16-bit dual-bank CMOS transceiver with independent direction and output-enable controls per bank, 3-state outputs, Schmitt-trigger inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V, delivers ±24 mA drive at 3.0 V, supports 50 Ω transmission line driving at 85 °C, and is rated for -40 °C to +85 °C ambient operation. It is used in bidirectional data bus interfacing between microcontrollers and peripheral memory or I/O subsystems.

For engineers reviewing the 74ALVC16245DGG,112 datasheet, 74ALVC16245DGG,112 pinout, 74ALVC16245DGG,112 application, or 74ALVC16245DGG,112 equivalent, key selection criteria include voltage range compatibility (1.2–3.6 V), dual 8-bit bank control granularity, IOFF-enabled safe power sequencing, overvoltage-tolerant inputs up to 5.5 V, and TSSOP48 package suitability for high-density PCB layouts.

Technical Context

This device implements two independent 8-bit transceiver banks (Bank 1: A0–A7/B0–B7; Bank 2: A0–A7/B0–B7), each with dedicated DIR and OE pins enabling flexible bidirectional data flow control. Its IOFF circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and partial-power-down systems.

Schmitt-trigger inputs ensure robust noise immunity against slow-rising/falling signals, while its 1.2 V minimum supply enables direct interface with low-voltage logic domains. The 74ALVC variant lacks bus-hold but supports 5.5 V-tolerant inputs; this specific part (74ALVC16245DGG) does not include bus-hold functionality.

FAQ

What is the maximum clock/data rate supported by the 74ALVC16245DGG,112?

The device does not operate on a clock; it is asynchronous. Its propagation delay ranges from 1.0 ns (typical) to 3.0 ns (max) at 3.3 V with 50 pF load, enabling reliable operation in systems with data valid windows ≥4 ns. System-level timing depends on external bus protocol and trace lengths - not internal clocking.

Can the 74ALVC16245DGG,112 be used with a 5 V microcontroller?

Yes - its inputs tolerate up to 5.5 V regardless of VCC voltage (1.2–3.6 V), allowing direct connection to 5 V logic outputs. However, its outputs swing only from GND to VCC, so external level-shifting is required if driving 5 V inputs. It is not a bidirectional level shifter.

Does this part include bus-hold circuitry?

No - the 74ALVC16245DGG,112 does not feature bus-hold. That function is exclusive to the 74ALVCH16245 variant. Unused inputs must be externally terminated with pull-up or pull-down resistors to prevent floating states and potential increased power consumption or logic errors.

How does IOFF protection work during power-down sequences?

When VCC drops below ~0.8 V, the IOFF circuit automatically disables all outputs, forcing them into high-impedance state regardless of OE/DIR pin states. This prevents current from flowing backward through I/O pins into a powered-down VCC rail - protecting both this device and upstream/downstream components during staggered power cycling.
