Nexperia USA Inc. 74LVC16244ADGVJ

Overview

74LVC16244ADGVJ from Nexperia is a 16-bit non-inverting 3-state buffer/line driver in TVSOP48 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It supports mixed-voltage interfacing between 3.3 V and 5 V systems in industrial I/O expansion and bus isolation applications.

For engineers reviewing the 74LVC16244ADGVJ datasheet, 74LVC16244ADGVJ pinout, 74LVC16244ADGVJ application, or 74LVC16244ADGVJ equivalent, this device is selected for high-density 16-bit bidirectional buffering where voltage translation, low static current (<20 μA), fast propagation delay (≤4.1 ns at 3.3 V), bus hold (on LVCH variant), 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), enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers. Each section features Schmitt-trigger inputs for reliable operation with slow-rising signals and IOFF circuitry that disables outputs and blocks backflow current when VCC = 0 V.

All 16 data inputs on the 74LVCH16244A variant include bus hold circuitry (not present on base 74LVC16244A), eliminating external pull-ups on unused inputs; the 74LVC16244ADGVJ is the LVC version - no bus hold - confirmed by pin description table and functional distinction in Section 1 and Table 6.

Key Specifications

Pinout & Package

74LVC16244ADGVJ uses the SOT480-1 package: TVSOP48, 48-pin plastic thin shrink small outline package with 0.4 mm lead pitch and 4.4 mm body width. Pin 1 index located at top-left corner; pins numbered counterclockwise.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.

Compared with 74LVCH16244ADGV, the 74LVC16244ADGVJ lacks bus hold but offers identical timing and drive - simplifying design when inputs are always driven. Versus SN74LVC16244ADGGR, the TVSOP48 package saves 35 % board area but requires tighter thermal design due to steeper power derating.

FAQ

Is 74LVC16244ADGVJ pin-compatible with 74LVCH16244ADGV?

Yes - both share identical SOT480-1 (TVSOP48) pinout, supply ranges, timing, and 3-state behavior. The sole functional difference is bus hold: absent on 74LVC16244ADGVJ, present on 74LVCH16244ADGV. No layout change is needed for substitution, though unused inputs on the LVC version require external termination.

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

This device does not operate on a clock; it is asynchronous. Its 4.1 ns max propagation delay at 3.3 V supports reliable data transfer up to ~100 MHz in parallel bus applications (e.g., 16-bit address/data strobes), assuming proper PCB layout, load capacitance ≤50 pF, and clean power delivery.

Can 74LVC16244ADGVJ drive 5 V TTL inputs safely?

Yes - its outputs are 5 V tolerant and deliver VOH ≥2.2 V at 24 mA into standard TTL loads (2.4 V min threshold). When VCC = 3.3 V, output swing remains compatible with TTL VIH (2.0 V min), and the 5 V-tolerant structure prevents damage even if loaded to 5 V rails.

Does this part support hot-swap insertion while system power is active?

Yes - the IOFF circuit actively disables outputs and blocks reverse current when VCC = 0 V, protecting upstream drivers during live insertion. This feature is validated per JEDEC JESD78 and confirmed in Section 1 and Table 6 of the datasheet for partial power-down operation.
