Product details

Overview

74LVCH16245ADL,112 from NXP Semiconductors is a 16-bit non-inverting bus transceiver with 3-state outputs, designed for bidirectional data flow between buses operating at different voltage levels (1.65 V to 3.6 V). It features ±24 mA drive strength, 3.6 ns typical propagation delay at 3.3 V, and supports hot insertion. Used in industrial PLC backplanes and FPGA I/O expansion interfaces.

For engineers reviewing the 74LVCH16245ADL,112 datasheet, 74LVCH16245ADL,112 pinout, 74LVCH16245ADL,112 application, or 74LVCH16245ADL,112 equivalent, key selection criteria include voltage translation capability, bus-hold functionality, output drive strength, and ESD tolerance per IEC 61000-4-2.

Technical Context

This transceiver integrates two independent 8-bit sections (A/B), each with direction control (DIR) and output enable (OE) inputs. All I/O pins are 5 V tolerant when V_CC = 3.3 V, enabling safe interfacing with legacy 5 V logic. Bus-hold circuitry eliminates external pull-up resistors on unused inputs.

It operates across ambient temperatures from –40 °C to +125 °C and meets AEC-Q100 Grade 2 reliability requirements. The device uses CMOS technology with TTL-compatible input thresholds and is specified for operation down to 1.65 V V_CC, supporting low-power system designs.

Key Specifications

V_CC Range	1.65 V to 3.6 V - enables interoperability between 1.8 V, 2.5 V, and 3.3 V logic domains
Propagation Delay	3.6 ns (typ) at V_CC = 3.3 V - supports high-speed data transfer up to 100 MHz bus rates
Output Drive	±24 mA - drives standard 50 Ω transmission lines or multiple CMOS loads without signal degradation
ESD Rating	±4 kV HBM - ensures robustness during board handling and system integration
Bus-Hold Input	Integrated on all I/O - maintains valid logic state on floating inputs, reducing BOM count and layout complexity
Operating Temp	–40 °C to +125 °C - qualified for under-hood automotive and industrial control environments

Pinout & Package

Supplied in a 48-pin TSSOP (Thin Shrink Small Outline Package) with 0.5 mm pitch, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A7	Data inputs/outputs (Port A)	Bidirectional I/O for first 8-bit bus segment; 5 V tolerant when V_CC ≤ 3.6 V
B0–B7	Data inputs/outputs (Port B)	Bidirectional I/O for second 8-bit bus segment; supports independent voltage domain interfacing
DIR	Direction control input	High = A→B data flow; Low = B→A; determines signal path direction per section
OE	Output enable input	Active-low; places both A and B ports in high-impedance state when asserted
V_CC	Supply voltage	Single supply for entire device; powers internal logic and I/O buffers
GND	Ground reference	Common return path for all signals and supply current

Key Features

Feature	Design Value
5 V tolerant I/O	Enables direct connection to 5 V peripherals without level-shifting components
Bus-hold circuitry	Eliminates need for external pull resistors on unused or unterminated data lines
Hot-insertion capability	Prevents bus contention and latch-up during live board insertion into powered backplanes

FAQ

What is the maximum data rate supported by the 74LVCH16245ADL,112?

The device supports reliable data transfer up to 100 MHz, based on its 3.6 ns typical propagation delay and 0.5 ns skew specification at 3.3 V V_CC. This allows full-cycle operation within a 10 ns clock period, making it suitable for high-speed parallel bus applications including memory-mapped I/O and FPGA interface extensions.

Does the 74LVCH16245ADL,112 require external pull-up resistors on unused inputs?

No. All I/O pins feature integrated bus-hold circuitry that actively maintains the last valid logic state without external components. This eliminates the need for pull-up or pull-down resistors on unconnected or intermittently driven lines, simplifying schematic design and reducing bill-of-materials count.

Can the 74LVCH16245ADL,112 interface a 3.3 V FPGA with a 5 V ADC?

Yes. Its I/O pins are 5 V tolerant when V_CC is between 1.65 V and 3.6 V, allowing safe connection to 5 V devices without external level shifters. The FPGA drives the transceiver's A-side at 3.3 V, and the transceiver drives the ADC's data bus at 5 V logic levels via its B-side outputs.

Is the 74LVCH16245ADL,112 compatible with hot-swap backplane insertion?

Yes. It incorporates power-off protection and hot-insertion circuitry that prevents bus contention and back-current flow when inserted into a live backplane. I/Os remain in high-impedance state until V_CC stabilizes, and inputs tolerate voltages beyond V_CC during ramp-up.
