Product details

Overview

74LVTH16244BBX,518 from NXP Semiconductors is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for high-speed 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 TTL-compatible control inputs.

For engineers reviewing the 74LVTH16244BBX,518 datasheet, 74LVTH16244BBX,518 pinout, 74LVTH16244BBX,518 application, or 74LVTH16244BBX,518 equivalent, key selection factors include 3-state enable timing, output drive capability at 3.3 V, bus hold functionality absence, and compatibility with LVT logic families in backplane and memory interface designs.

Technical Context

This device integrates two independent 8-bit buffer sections, each with separate Output Enable (OE) controls. All inputs are TTL-compatible, and outputs are fully 3.3 V CMOS-compatible with rail-to-rail swing and guaranteed low-impedance active and high-impedance off states.

Propagation delay is specified at 2.9 ns (max) at V_CC = 3.3 V and T_A = 25 °C, with input hysteresis of 0.5 V typical on OE pins to improve noise immunity. The device lacks bus-hold or power-down features and is not specified for hot-swap operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 3.6 V - ensures interoperability with 3.3 V systems while tolerating supply variation
Output Drive	±64 mA - enables direct driving of heavy capacitive loads (e.g., >50 pF traces or multiple inputs)
Propagation Delay	2.9 ns max - supports >300 MHz bus toggle rates in point-to-point configurations
Input Compatibility	TTL - accepts standard 5 V logic thresholds without level-shifting circuitry
Output Type	3-state CMOS - allows bidirectional bus sharing with controlled contention avoidance
Operating Temp	−40 °C to +85 °C - qualified for industrial ambient environments without derating

Pinout & Package

74LVTH16244BBX,518 is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package) with 0.5 mm pitch, optimized for high-density PCB layouts and automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1A1–1A8, 2A1–2A8	Input	Eight dedicated inputs per section; no internal pull-ups or bus-hold
1Y1–1Y8, 2Y1–2Y8	Output	Non-inverting buffered outputs with 3-state control; sink/source capable
1OE, 2OE	Active-Low Enable	Independent section control; TTL-compatible threshold, hysteresis improves noise margin
V_CC, GND	Power	Single 3.3 V supply; decoupling required per section due to high di/dt

Key Features

Feature	Design Value
High-Speed Operation	2.9 ns propagation delay enables use in 300+ MHz address/data buses
Strong Output Drive	±64 mA per output supports fan-out to ≥10 LVT loads or long trace routing
TTL-Compatible Inputs	Accepts 5 V logic signals directly-eliminates need for external level shifters
Low-Voltage 3.3 V Operation	Guaranteed function down to 2.7 V-supports brown-out tolerant system designs

Applications

Memory Interface Buffering

Backplane Data Distribution

Use Scenario: Driving parallel SRAM or Flash data/address buses across multi-layer PCBs with >30 cm trace lengths.

IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state control synchronizes with memory read/write strobes.

Use Value: ±64 mA drive maintains signal integrity at 200+ MHz toggle rates without external termination.

Use Scenario: Fan-out of control/status signals from a central controller to multiple slot cards in a modular chassis.

IC Role / Device Role / Timing Role: Level-translating repeater between TTL-based control logic and 3.3 V peripheral modules.

Use Value: TTL-compatible inputs accept legacy 5 V control signals; 3.3 V outputs interface safely with modern modules.

Industrial PLC I/O Expansion

Test Equipment Signal Conditioning

Use Scenario: Isolating and buffering digital I/O lines between microcontroller GPIO and field-side optocouplers or relays.

IC Role / Device Role / Timing Role: Directional signal conditioner with enable-controlled isolation during reset or fault conditions.

Use Value: Independent OE pins allow per-section shutdown-prevents bus contention during partial system reconfiguration.

Use Scenario: Amplifying and conditioning low-amplitude digital stimulus signals before ATE pattern generators.

IC Role / Device Role / Timing Role: High-fidelity waveform repeater preserving edge rate and logic threshold accuracy.

Use Value: 2.9 ns delay matching and low skew (<0.3 ns) ensure precise timing alignment across 16 channels.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16244ADGGR	Lower drive (±24 mA), 1.65–3.6 V supply, no TTL input compatibility	Requires level-shifting for 5 V inputs; suitable only in pure 3.3 V or mixed-voltage systems with translation	Select when lower power and smaller footprint outweigh drive strength and TTL interface needs
74ALVCH16244DGG,118	Higher speed (2.3 ns), same drive and voltage range, but requires 1.65–3.6 V and has different OE timing specs	Not drop-in compatible due to tighter setup/hold requirements on OE relative to clock domains	Choose only after verifying timing margins in synchronous enable-controlled bus architectures

Compared with SN74LVC16244ADGGR and 74ALVCH16244DGG,118, the 74LVTH16244BBX,518 uniquely combines TTL input compatibility, ±64 mA drive, and 2.9 ns delay-making it optimal for legacy 5 V control interfacing to 3.3 V buses where signal integrity and timing margin are critical.

FAQ

Is 74LVTH16244BBX,518 pin-compatible with standard 74-series 16-bit buffers?

No. While functionally similar to 74LVC16244 and 74ALVCH16244, the 74LVTH16244BBX,518 uses a 48-pin TSSOP package with unique pin mapping-including separate OE pins per 8-bit section and dedicated V_CC/GND pairs per section-not shared with industry-standard 48-pin SO or TSSOP variants of other families.

Does this device include bus-hold or power-down circuitry?

No. The 74LVTH16244BBX,518 does not incorporate bus-hold (I^OH/I^OL bias) or power-down (zero-current standby) features. Inputs float when un-driven, and outputs enter high-impedance state only when OE is asserted-no automatic input stabilization or quiescent current reduction is provided.

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

Based on its ±64 mA output drive and 2.9 ns propagation delay, the device reliably drives up to 100 pF total load capacitance while maintaining <1 ns output rise/fall time and <0.3 ns inter-output skew under worst-case V_CC and temperature conditions.

Can 74LVTH16244BBX,518 be used in hot-swap applications?

No. The device is not characterized or rated for hot-swap operation. It lacks I_ON current limiting, power-up sequencing control, or ESD-protected I/O structures required for live insertion-use only in systems with controlled power sequencing and static-safe handling protocols.
