Nexperia USA Inc. 74LVC16244ADL,118

Overview

74LVC16244ADL,118 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver with four independent output-enable inputs (1OE–4OE), 5 V tolerant I/O, Schmitt-trigger inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage interfacing between 3.3 V and 5 V systems, and is qualified for -40 °C to +125 °C ambient operation. Used in high-density data bus buffering for industrial control backplanes and FPGA I/O expansion.

For engineers reviewing the 74LVC16244ADL,118 datasheet, 74LVC16244ADL,118 pinout, 74LVC16244ADL,118 application, or 74LVC16244ADL,118 equivalent, this device delivers deterministic 3-state timing, bus hold functionality (on 74LVCH variant), and robust 5 V tolerance without level shifters-critical for legacy interface bridging and hot-swap-capable peripheral isolation.

Technical Context

This device implements four independent 4-bit buffer sections, each with dedicated active-low output enable (nOE) controlling four outputs (nY0–nY3). All inputs feature Schmitt-trigger action, enabling reliable operation with slow-rising signals and noise margin up to 0.4 V at VCC = 3.3 V.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences. Input voltage range spans -0.5 V to 5.5 V, and output drive capability reaches ±24 mA at VCC = 3.0 V with VOL ≤ 0.55 V and VOH ≥ 2.2 V under load.

FAQ

Is 74LVC16244ADL,118 pin-compatible with 74LVCH16244ADL,118?

Yes-both share identical TSSOP48 (SOT362-1) pinout, supply range, and functional behavior. The only difference is that the LVCH variant adds bus hold circuitry on data inputs; control inputs (OE) remain unchanged. No PCB redesign is needed when substituting between them.

Can 74LVC16244ADL,118 drive a 50 Ω transmission line directly?

Yes-its ±24 mA output drive at VCC = 3.0 V supports termination into 50 Ω with VOL ≤ 0.55 V and VOH ≥ 2.2 V. For clean edge integrity beyond 10 cm, add series source termination (22–33 Ω) near the driver output to damp reflections.

What is the maximum clock/data rate supported by this buffer?

With tpd ≤ 5.5 ns (VCC = 3.3 V), the device supports data rates up to ~100 MHz in point-to-point configurations. For bus applications, derate based on capacitive loading: CPD = 11.4 pF and typical trace + load capacitance must stay below 30 pF for sub-ns skew across all 16 bits.

Does 74LVC16244ADL,118 require external pull-up resistors on unused inputs?

No-Schmitt-trigger inputs have defined thresholds and do not float unpredictably. However, for best noise immunity in high-EMI environments, tie unused inputs to VCC or GND. Unlike the LVCH variant, this part does not include bus hold, so intentional floating is discouraged.
