Nexperia USA Inc. 74LVTN16244BDGG,12

Overview

74LVTN16244BDGG,12 from Nexperia is a 3.3 V, 16-bit non-inverting buffer/driver with 3-state outputs, implemented in high-performance BiCMOS technology. It functions as four independent 4-bit buffers (each with dedicated active-low output enable), supports mixed-voltage interfacing (5 V-tolerant inputs/outputs), delivers ±32 mA/±64 mA drive strength, and operates across -40 °C to +85 °C for industrial bus interface applications.

For engineers reviewing the 74LVTN16244BDGG,12 datasheet, 74LVTN16244BDGG,12 pinout, 74LVTN16244BDGG,12 application, or 74LVTN16244BDGG,12 equivalent, key selection considerations include 3-state timing (tPZH ≤ 4.0 ns), 5 V input tolerance, power-up 3-state behavior, and TSSOP48 thermal performance under sustained 64 mA sink loads.

Technical Context

This device implements four independent 4-bit non-inverting buffer sections, each with a dedicated active-low output enable (1OE–4OE). Each section drives four outputs (e.g., 1Y0–1Y3) from corresponding inputs (1A0–1A3), supporting flexible partitioning as one 16-bit, two 8-bit, or four 4-bit buses.

It features TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), 5 V-tolerant I/O (VI/VO up to 7.0 V), and BiCMOS output stages enabling +64 mA sink and -32 mA source capability at VCC = 3.0 V, with guaranteed VOL ≤ 0.55 V at 64 mA sink.

FAQ

Is the 74LVTN16244BDGG,12 compatible with 5 V microcontrollers without level shifters?

Yes. Its inputs are 5 V-tolerant (VI up to 5.5 V recommended, 7.0 V absolute max), and outputs drive 5 V buses directly due to BiCMOS output stage design. No external level-shifting components are needed when interfacing with 5 V logic, provided VCC remains at 3.3 V ±0.3 V.

What is the maximum capacitive load this device can drive while maintaining specified timing?

The datasheet specifies dynamic characteristics with CL = 50 pF (Table 9). At that load, tPLH/tPHL ≤ 3.2 ns is guaranteed. Driving >50 pF increases propagation delay nonlinearly; for 100 pF loads, empirical testing shows tPLH increases to ~5.8 ns at VCC = 3.3 V and Tamb = 25 °C.

Does the device support hot-swap in backplane applications?

Yes. It supports live insertion and extraction per datasheet Section 2, enabled by latch-up protection (JESD78B Class II > 500 mA) and ESD-hardened I/O (HBM > 2000 V). Power-up 3-state behavior prevents bus contention during insertion, and IOFF leakage remains ≤ ±100 μA when VCC = 0 V.

How many GND and VCC pins does the TSSOP48 package have, and why?

The TSSOP48 package has eight GND pins (4, 10, 15, 21, 28, 34, 39, 45) and four VCC pins (7, 18, 31, 42). This distribution minimizes ground bounce and supply inductance, ensuring signal integrity for all 16 outputs switching simultaneously at sub-5 ns edges - critical for noise-sensitive industrial environments.
