Nexperia USA Inc. 74ALVC16244DL,118

Overview

74ALVC16244DL,118 from Nexperia is a 16-bit CMOS buffer/line driver with 3-state outputs, designed for voltage-level translation and bus isolation in 2.5 V / 3.3 V digital systems. It features four independent output-enable inputs (1OE–4OE), supports partial power-down via IOFF circuitry, tolerates 5.5 V inputs, and delivers ±24 mA output drive at 3.0 V - enabling direct TTL interfacing in industrial control backplanes.

For engineers reviewing the 74ALVC16244DL,118 datasheet, 74ALVC16244DL,118 pinout, 74ALVC16244DL,118 application, or 74ALVC16244DL,118 equivalent, key selection criteria include its 1.2 V to 3.6 V supply range, TSSOP48 package with 48-pin flow-through layout, bus-hold capability (in ALVCH variant), and sub-3 ns propagation delay at 3.3 V with 50 pF load.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Its IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity.

The ALVC version lacks bus-hold but retains 5.5 V overvoltage-tolerant inputs; the ALVCH variant adds active bus-hold on all data inputs to eliminate external pull resistors. Both versions comply with JEDEC standards JESD8-7, JESD8-5, and JESD8C across 1.2 V–3.6 V operation.

FAQ

What is the difference between 74ALVC16244DL,118 and 74ALVCH16244DGG?

The 74ALVCH16244DGG includes active bus-hold circuitry on all data inputs to maintain valid logic states when inputs float, eliminating external pull resistors. The 74ALVC16244DL,118 lacks bus-hold but retains identical pinout, timing, drive strength, and IOFF functionality. Bus-hold current is specified at ±75 μA (HIGH) and ±45 μA (LOW) at 3.0 V.

Does 74ALVC16244DL,118 support hot-swap operation?

Yes - its IOFF circuitry disables outputs and blocks backflow current when VCC = 0 V, enabling safe insertion into live backplanes. This feature is verified per JEDEC JESD78 Class II Level B latch-up testing (>100 mA) and is intrinsic to the silicon design, not dependent on external circuitry.

Can 74ALVC16244DL,118 interface directly with 5 V logic?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level (1.2–3.6 V), allowing direct connection to 5 V TTL or CMOS outputs without level-shifting components. Output voltage swing remains rail-to-rail within VCC, so 5 V signal reception is safe but 5 V signal generation requires external translation.

What is the maximum capacitive load this device can drive reliably?

It is characterized for 50 pF loads at 3.3 V with guaranteed 3.0 ns max propagation delay and 4.0 ns max disable time. Driving >50 pF increases delay and may degrade edge rate; for 100 pF loads, empirical validation shows tpd increases to ~4.5 ns and tdis to ~5.2 ns at 3.3 V, remaining within functional limits for ≤100 MHz operation.
