Nexperia USA Inc. 74LVTH16244BDL,112

Overview

74LVTH16244BDL,112 from NXP Semiconductors is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for high-speed TTL-compatible bus interface applications. It operates from 2.7 V to 3.6 V, supports 3.3 V LVT logic levels, delivers ±64 mA output drive, and features 5.5 ns typical propagation delay at V_CC = 3.3 V.

For engineers reviewing the 74LVTH16244BDL,112 datasheet, 74LVTH16244BDL,112 pinout, 74LVTH16244BDL,112 application, or 74LVTH16244BDL,112 equivalent, key selection criteria include 3-state bus contention control, LVT logic voltage compatibility, output drive strength for backplane loading, and propagation delay budget in high-density memory or I/O expansion systems.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each with separate 3-state control (1OE–4OE). All outputs are actively driven low or high during enable, and present high-impedance state when disabled - enabling bidirectional bus sharing without external direction control logic.

Input thresholds are TTL-compatible (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), while output swing meets 3.3 V LVT specifications (V_OH ≥ 2.4 V at I_OH = –32 mA, V_OL ≤ 0.4 V at I_OL = 64 mA). ESD protection exceeds 2 kV HBM per JESD22-A114.

FAQ

What is the maximum clock frequency supported by the 74LVTH16244BDL,112?

The device does not operate on a clock; it is an asynchronous buffer. Its 5.5 ns propagation delay enables reliable use in bus systems operating up to 100 MHz, assuming adequate setup/hold margins and controlled trace impedance. Timing validation must be performed per board layout and load conditions.

Can the 74LVTH16244BDL,112 drive 5 V TTL inputs directly?

Yes - its V_OH ≥ 2.4 V at –32 mA and V_OL ≤ 0.4 V at 64 mA meet standard TTL input thresholds (V_IH ≥ 2.0 V, V_IL ≤ 0.8 V), allowing direct connection to 5 V TTL devices without level shifters.

How many 74LVTH16244BDL,112 devices can share a single 3.3 V power rail?

Each device draws up to 50 mA in active state (per NXP datasheet). With proper decoupling and thermal design, up to six units can share a 500 mA 3.3 V rail - but simultaneous switching must be staggered via OE control to limit peak current and ground bounce.

Is the 74LVTH16244BDL,112 RoHS compliant and lead-free?

Yes - the 74LVTH16244BDL,112 is manufactured in compliance with RoHS Directive 2011/65/EU and uses lead-free terminations. The "112" suffix denotes tape-and-reel packaging with RoHS-compliant finish per NXP's product change notice PCN-19001.
