Nexperia USA Inc. 74LVT16244BDGG,118

Overview

74LVT16244BDGG,118 from Nexperia is a 3.3 V, 16-bit non-inverting 3-state buffer/driver in TSSOP48 package, featuring four independent output-enable controls (1OE–4OE), bus-hold inputs eliminating external pull-ups, and ±32 mA/±64 mA drive capability. It operates from 2.7 V to 3.6 V, tolerates 5.5 V inputs, and supports high-speed data routing in backplane and memory interface applications.

For engineers reviewing the 74LVT16244BDGG,118 datasheet, 74LVT16244BDGG,118 pinout, 74LVT16244BDGG,118 application, or 74LVT16244BDGG,118 equivalent, key selection criteria include 3-state timing (tPZH ≤ 4.0 ns), overvoltage-tolerant inputs, bus-hold current specs (IBHL = 75–135 μA), and thermal performance across –40 °C to +85 °C.

Technical Context

This BiCMOS device implements four independent 4-bit buffer sections, each with dedicated active-low output enable (nOE). Each section drives four outputs (nY0–nY3) from corresponding inputs (nA0–nA3), supporting flexible partitioning as one 16-bit, two 8-bit, or four 4-bit buffers.

Bus-hold circuitry maintains valid logic states on unused inputs without external resistors; IOFF protection enables partial power-down operation when VCC = 0 V; and overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V buses while powered from 3.3 V.

FAQ

What is the maximum clock frequency supported by the 74LVT16244BDGG,118?

The device does not operate synchronously and has no clock input; its usable data rate depends on propagation delay and load. With tPLH/tPHL ≤ 3.2 ns and typical trace capacitance, it reliably supports data bus frequencies up to 200 MHz in point-to-point configurations and ~100 MHz across 15 cm routed traces with proper termination.

Can the 74LVT16244BDGG,118 be used with a 5 V microcontroller driving its inputs?

Yes - all inputs tolerate up to 5.5 V regardless of VCC level (2.7–3.6 V), enabling direct connection to 5 V TTL or CMOS outputs without level shifters. The outputs remain 3.3 V compatible, so downstream devices must accept 3.3 V logic levels.

How does the bus-hold function behave when an input is left unconnected?

Each input retains its last valid logic state via internal feedback circuitry drawing 75–135 μA (LOW) or –135 to –75 μA (HIGH). This prevents metastability and unintended toggling without external pull resistors, reducing component count and improving reliability in high-density layouts.

Is the 74LVT16244BDGG,118 pin-compatible with the older 74LVT16244BDL (SSOP48)?

No - the 74LVT16244BDGG uses TSSOP48 (SOT362-1) with 0.5 mm pitch and 6.1 mm body width, while the discontinued 74LVT16244BDL used SSOP48 (SOT370-1) with 0.635 mm pitch and 7.5 mm width. Footprints and reflow profiles are incompatible; redesign is required for migration.
