Product details
Overview
SN74LVTH162240DL from Texas Instruments is a 3.3-V ABT 16-bit inverting buffer/driver with 3-state outputs, designed for low-voltage bus driving in memory address, clock, and data paths. It features four independent 4-bit sections, each with active-low output-enable (OE), 22-Ω integrated series output resistors, and bus-hold on all inputs. It supports mixed-mode operation with 5-V tolerant inputs while powered from 2.7–3.6 V.
For engineers reviewing the SN74LVTH162240DL datasheet, SN74LVTH162240DL pinout, SN74LVTH162240DL application, or SN74LVTH162240DL equivalent, key selection criteria include its 48-pin SSOP (DL) package, –40°C to 85°C operating range, 12-mA output drive capability, TTL-compatible 3.3-V logic interface, and hot-insertion support via Ioff and power-up 3-state.
Technical Context
The SN74LVTH162240DL implements an Advanced BiCMOS Technology (ABT) architecture optimized for 3.3-V operation with low static power and high-speed switching. Its four independent 4-bit inverting buffers each accept TTL-level inputs and deliver symmetrical active-low OE control, enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers.
Each output integrates a 22-Ω series resistor to suppress overshoot/undershoot without external components, and all data inputs feature bus-hold circuitry to maintain valid logic states when floating. The device guarantees hot-insertion compatibility through Ioff protection and power-up 3-state behavior, ensuring outputs remain high-impedance during VCC ramp from 0 to 1.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 3.6 V - Enables stable operation across unregulated battery rails down to 2.7 V. |
| Output Drive Strength | ±12 mA - Sufficient to directly drive standard TTL loads without external buffering. |
| Propagation Delay (tPLH/tPHL) | 2.5 ns typical at VCC = 3.3 V - Supports high-speed bus timing in 100+ MHz systems. |
| Input Voltage Tolerance | 0 V to 5.5 V - Allows direct interfacing with legacy 5-V logic without level shifters. |
| Bus-Hold Current | ±750 µA max - Eliminates need for external pullup/pulldown resistors on unused inputs. |
| Output Enable Propagation (tPZL/tPHZ) | 2.8 ns typical - Ensures fast, glitch-free bus arbitration during enable/disable transitions. |
| Quiescent Supply Current | 0.19 mA - Minimizes standby power in always-on embedded control subsystems. |
Pinout & Package
SN74LVTH162240DL is housed in a 48-pin Shrink Small-Outline Package (SSOP-DL), 12.6 mm × 6.2 mm × 1.95 mm body, with 0.5-mm lead pitch and gull-wing leads. Pin 1 is marked by a beveled corner and located in Quadrant Q1 per tape-and-reel orientation.

| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enables | Independent OE per 4-bit section enables granular bus isolation and power gating. |
| VCC (Pins 7, 15, 23, 31, 39) | Power Supply | Distributed VCC pins minimize simultaneous switching noise and improve PDN stability. |
| GND (Pins 4, 12, 20, 28, 36, 45) | Ground Reference | Six GND pins provide low-inductance return paths and reduce ground bounce (VOLP < 0.8 V). |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Non-inverting, LVC family, lower drive (24 mA), no bus-hold, no integrated 22-Ω resistors. | Requires external termination and pullups; suited for non-inverting bus buffering where polarity preservation is required. | Select when inverting logic is not needed and higher output current is prioritized over built-in termination. |
| SN74LVTH162244DLR | Non-inverting version of same ABT family; identical pinout, package, and electrical specs except output polarity. | Direct functional replacement where signal inversion must be avoided (e.g., clock distribution without phase inversion). | Choose for drop-in replacement where output polarity must match upstream logic without redesigning signal flow. |
Compared with SN74LVTH162240DL, SN74LVC16244ADGGR offers higher drive but lacks bus-hold and integrated termination-increasing BOM and layout complexity-while SN74LVTH162244DLR provides identical performance with non-inverting outputs, enabling immediate reuse of PCB layout when polarity is critical.

Does SN74LVTH162240DL support hot-plug insertion?
Yes, SN74LVTH162240DL supports hot insertion via dual protection mechanisms: Ioff circuitry disables outputs when VCC = 0 V to prevent backflow current, and power-up 3-state ensures outputs remain high-impedance during VCC ramp from 0 to 1.5 V-both verified in the Absolute Maximum Ratings and Recommended Operating Conditions tables.
What package type is used for SN74LVTH162240DL?
SN74LVTH162240DL uses the SSOP (Shrink Small-Outline Package) with designation DL, a 48-pin gull-wing surface-mount package measuring 12.6 mm × 6.2 mm × 1.95 mm, with 0.5-mm lead pitch and RoHS-compliant NiPdAu lead finish per TI's packaging addendum.
Can SN74LVTH162240DL interface with 5-V logic systems?
Yes, SN74LVTH162240DL accepts input voltages up to 5.5 V while operating from a 3.3-V supply, enabling direct TTL-level interfacing with 5-V systems without external level shifters-confirmed in the Recommended Operating Conditions table under "VI (Input voltage)" parameter.
How many independent output-enable controls does SN74LVTH162240DL have?
SN74LVTH162240DL has four independent active-low output-enable inputs (1OE, 2OE, 3OE, 4OE), each controlling a separate 4-bit buffer section-enabling selective bus isolation, power gating, and flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers per the Functional Description and Logic Diagram.
