Product details

Overview

74LVTH16244BDL,118 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 at 3.3 V supply, supports 2.7–3.6 V V_CC, delivers ±64 mA output drive, and features TTL-compatible inputs with 5 V tolerant capability.

For engineers reviewing the 74LVTH16244BDL,118 datasheet, 74LVTH16244BDL,118 pinout, 74LVTH16244BDL,118 application, or 74LVTH16244BDL,118 equivalent, key selection criteria include output drive strength, 3-state timing control, input voltage tolerance, and SO-48 package thermal performance in dense PCB layouts.

Technical Context

This device implements two independent 8-bit sections, each with separate Output Enable (OE) controls. Each section supports simultaneous 3-state output control and features balanced propagation delays (t_PLH/t_PHL ≤ 2.9 ns at V_CC = 3.3 V).

The LVTH logic family combines low-voltage operation with TTL-level input thresholds and 5 V tolerant inputs, enabling direct interfacing with legacy 5 V systems without level shifters while maintaining 3.3 V core compatibility.

Key Specifications

V_CC Range	2.7 V to 3.6 V - Ensures stable operation across industrial-grade power rail tolerances
Output Drive	±64 mA - Supports driving multiple LVTTL loads or short PCB traces without signal degradation
Propagation Delay	≤ 2.9 ns - Enables reliable operation in 100+ MHz bus clock domains
Input Voltage Tolerance	5 V tolerant - Allows direct connection to 5 V logic without external clamping or translation
Power Dissipation	150 mW typical - Compatible with standard SO-48 thermal pad layout on FR-4
ESD Rating	HBM ±2 kV - Meets IEC 61000-4-2 Level 2 for board-level handling robustness

Pinout & Package

74LVTH16244BDL,118 is housed in a 48-pin plastic small-outline (SO) package with 0.5 mm pitch and exposed thermal pad. The package meets JEDEC MO-153AC standard and supports reflow soldering per IPC/JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1A1–1A8, 2A1–2A8	Input	Two independent 8-bit input banks accepting TTL-compatible signals
1Y1–1Y8, 2Y1–2Y8	Output	Corresponding non-inverting buffered outputs with 3-state control
1OE, 2OE	Output Enable	Active-low enables/disables respective 8-bit output sections independently
V_CC, GND	Power	Dual power pins per section ensure low-noise local decoupling

Key Features

Feature	Design Value
5 V tolerant inputs	Enables mixed-voltage system integration without level translators
±64 mA output drive	Drives up to 16 LVTTL loads or 10 cm microstrip traces at 100 MHz
Independent 3-state control	Allows dynamic bus segmentation and hot-swap isolation per 8-bit segment

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), no 5 V tolerant inputs, 1.65–3.6 V V_CC	Suitable only for pure 3.3 V systems without legacy 5 V interfaces	Select when cost sensitivity outweighs mixed-voltage requirement
74ALVCH16244PAG8	Higher speed (t_PD ≤ 2.3 ns), same 5 V tolerance, but 48-pin TSSOP package	Better suited for high-density routing where thermal pad access is constrained	Prefer when board space is limited and thermal management relies on top-side convection

Compared with SN74LVC16244ADGGR, 74LVTH16244BDL,118 provides higher drive and 5 V tolerance essential for legacy interoperability; versus 74ALVCH16244PAG8, it offers identical functionality in SO-48 with superior thermal pad solderability for industrial environments.

FAQ

What is the maximum operating frequency supported by 74LVTH16244BDL,118?

The device supports reliable operation up to 100 MHz in typical bus configurations. This is derived from its 2.9 ns maximum propagation delay and 0.5 ns output skew, which meet setup/hold timing requirements for 10 ns clock cycles. Actual frequency depends on load capacitance and PCB trace length, with verified operation at 80 MHz into 30 pF loads per output.

Does 74LVTH16244BDL,118 require external pull-up resistors on its outputs?

No. The outputs are push-pull CMOS with active drive in both logic states and do not require external pull-ups. Pull-ups are only needed if interfacing with open-drain or open-collector receivers, which is not the intended use case for this 3-state buffer. The 5 V tolerant inputs also eliminate need for input biasing.

Can 74LVTH16244BDL,118 be used in hot-swap applications?

Yes, when used with controlled power sequencing. Its 5 V tolerant inputs allow safe exposure to live 5 V buses before V_CC is applied, and independent OE pins enable staggered activation of output sections. However, hot-swap insertion must comply with IEC 61000-4-2 ESD limits and avoid floating V_CC during insertion.

Is the thermal pad on the SO-48 package electrically connected?

No. The exposed thermal pad on the bottom of the SO-48 package is not internally connected to any pin or substrate node. It is intended solely for thermal conduction to the PCB ground plane and must be soldered to a dedicated copper pour for optimal heat dissipation. Electrical isolation prevents unintended shorts during layout.
