Nexperia USA Inc. 74LVT16245BDGG,112

Overview

74LVT16245BDGG,112 from Nexperia is a 3.3 V 16-bit bidirectional transceiver with dual 3-state control (1OE/2OE) and dual direction control (1DIR/2DIR), supporting two independent 8-bit data paths or unified 16-bit operation. It features bus hold inputs eliminating external pull-ups, ±64 mA output drive, 5.5 V-tolerant inputs, and operates from -40 °C to +85 °C in TSSOP48 package. Used in high-speed 3.3 V backplane and memory interface buffering.

For engineers reviewing the 74LVT16245BDGG,112 datasheet, 74LVT16245BDGG,112 pinout, 74LVT16245BDGG,112 application, or 74LVT16245BDGG,112 equivalent, key selection criteria include bidirectional 3-state timing (tPLH/tPHL ≤ 3.3 ns at 3.3 V), overvoltage-tolerant I/O for mixed-voltage interconnects, bus hold functionality, and thermal performance under industrial ambient conditions.

Technical Context

This BiCMOS transceiver implements two independent 8-bit bidirectional data channels, each controlled by dedicated OE and DIR signals. Its bus hold circuitry actively maintains logic state on unused inputs without external components, reducing BOM count and layout complexity.

It supports live insertion/extraction and includes IOFF partial power-down protection, ensuring no current flows between powered and unpowered sections of a bus. The device complies with JEDEC JESD8C (2.7–3.6 V) and exceeds JESD78 Class II latch-up immunity (>500 mA).

FAQ

What is the maximum clock frequency supported by the 74LVT16245BDGG,112?

The device does not operate on a clock; it is an asynchronous transceiver. Its 3.3 ns max propagation delay (tPLH/tPHL at VCC = 3.3 V) supports data rates exceeding 200 MHz in point-to-point configurations with proper termination and trace length control. System-level timing depends on bus loading, PCB layout, and driver/receiver characteristics.

Can the 74LVT16245BDGG,112 safely interface between a 3.3 V microcontroller and a 5 V ADC?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level, allowing direct connection to 5 V outputs. Outputs swing rail-to-rail within the 3.3 V domain, so the 5 V ADC must accept 3.3 V logic-high levels (VIH ≥ 2.0 V), which most modern 5 V ADCs do. No level shifter is needed for this direction.

Does the bus hold feature eliminate all need for external pull-up/pull-down resistors?

Bus hold actively maintains the last valid logic state on unused inputs, removing the need for external pull-ups on those pins. However, pull-downs may still be required on control inputs (e.g., OE, DIR) if their default state must be LOW, as bus hold only engages after initial logic transition and does not override externally driven signals.

Is the 74LVT16245BDGG,112 qualified for automotive applications?

No - this part is specified for industrial temperature range (-40 °C to +85 °C) and is not AEC-Q100 qualified. Nexperia explicitly states non-automotive qualification in its legal disclaimers.
