Nexperia USA Inc. 74LVC16244ADGG,118

Overview

74LVC16244ADGG,118 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver in TSSOP48 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity. It supports mixed-voltage translation between 3.3 V and 5 V logic domains in industrial bus interface applications.

For engineers reviewing the 74LVC16244ADGG,118 datasheet, 74LVC16244ADGG,118 pinout, 74LVC16244ADGG,118 application, or 74LVC16244ADGG,118 equivalent, this device is selected for high-density bidirectional data buffering in memory expansion, FPGA I/O expansion, and industrial control backplanes where voltage-level translation, low static current (<20 μA), and robust ESD protection (HBM >2000 V) are critical.

Technical Context

This device implements four independent 4-bit buffer sections, each controlled by a dedicated active-low output enable (1OE–4OE). Each section propagates input signals (1A0–1A3, etc.) to corresponding outputs (1Y0–1Y3, etc.) with propagation delay as low as 1.0 ns at VCC = 2.7 V–3.6 V.

The IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, preventing backflow current during partial power-down. All 16 data inputs feature Schmitt-trigger action, enabling reliable operation with slow-rising or noisy signals, and the 74LVCH variant adds bus-hold circuitry - though the 74LVC16244A (this part) does not include bus hold.

FAQ

Is the 74LVC16244ADGG,118 pin-compatible with the 74LVCH16244ADGG?

Yes - both share identical TSSOP48 (SOT362-1) pinout, supply voltage range, and functional behavior. The only difference is that the 74LVCH variant includes bus-hold circuitry on all 16 data inputs, while the 74LVC version does not. No PCB redesign is needed for substitution if bus-hold is not required.

Can this device safely interface a 3.3 V microcontroller with a 5 V peripheral?

Yes - all inputs and outputs are rated for 5.5 V maximum, allowing direct connection to 5 V logic without external level shifters. The device operates from 1.2 V to 3.6 V supply, so it functions correctly at 3.3 V while tolerating 5 V signals on any I/O pin, satisfying mixed-voltage translation requirements.

What is the purpose of the IOFF feature, and how does it behave during power-down?

The IOFF circuit disables outputs when VCC = 0 V, limiting OFF-state leakage to ±10 μA max. This prevents backflow current from live 5 V buses into unpowered circuitry - critical for hot-swap, modular systems, and partial power-down states where some rails remain active while others are shut down.

Does this part include Schmitt-trigger inputs, and what benefit does that provide?

Yes - all 16 data inputs incorporate Schmitt-trigger action with typical hysteresis of ~0.3 V. This improves noise immunity on slow-rising signals (e.g., from mechanical switches or long cables) and eliminates false triggering caused by ringing or ground bounce, making it suitable for industrial environments with electrically noisy buses.
