Product details
Overview
SN74LVT16240DGGR from Texas Instruments is a 3.3-V ABT 16-bit inverting buffer/driver with 3-state outputs, designed for memory address, clock, and bus interface applications in mixed-voltage systems. It supports 5-V input compatibility with 3.3-V VCC, delivers ±64 mA output drive, operates from –40°C to 85°C, and features Ioff and power-up 3-state for hot-insertion.
For engineers reviewing the SN74LVT16240DGGR datasheet, SN74LVT16240DGGR pinout, SN74LVT16240DGGR application, or SN74LVT16240DGGR equivalent, key selection criteria include 3.3-V operation with 5-V tolerant inputs, symmetrical active-low OE control per 4-bit section, distributed VCC/GND for noise reduction, and TSSOP-48 packaging for high-density PCB layouts.
Technical Context
The SN74LVT16240DGGR implements four independent 4-bit inverting buffers, each with dedicated active-low output-enable (OE) inputs (1OE–4OE). Its Advanced BiCMOS Technology (ABT) enables low static power at 3.3 V while maintaining TTL-compatible thresholds and robust 5-V signal handling on inputs.
It integrates distributed power/ground pins, flow-through pin architecture, and Ioff circuitry to prevent backflow during power-down. The device enters high-impedance state when VCC is below 1.5 V or when OE is asserted low, supporting hot-swap and system-level power sequencing requirements without external protection.

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 |
|---|---|---|---|
| SN74LVTH16240DGGR | Lower drive (±32 mA), LVTH CMOS process, no 5-V input tolerance | Suitable only for pure 3.3-V systems; not interoperable with 5-V buses | Select when cost and power are prioritized over mixed-voltage compatibility |
| 74ALVC16240PW | 3.3-V only, ±24 mA drive, smaller TSSOP-48 package (5.5 mm width), no Ioff | Lacks hot-insertion support and 5-V input tolerance; limited to low-noise, low-capacitance interfaces | Choose for space-constrained consumer designs where full industrial robustness is unnecessary |
Compared with SN74LVT16240DGGR, SN74LVTH16240DGGR reduces power but sacrifices 5-V interface capability and hot-swap safety, while 74ALVC16240PW trades drive strength and Ioff protection for footprint reduction-making SN74LVT16240DGGR the optimal choice for industrial bus and memory applications requiring interoperability, ruggedness, and timing margin.

FAQ
What is the maximum operating voltage for SN74LVT16240DGGR?
The absolute maximum supply voltage (VCC) for SN74LVT16240DGGR is 4.6 V, but its recommended operating range is 2.7 V to 3.6 V. Operation outside this range may cause permanent damage or unpredictable behavior. The device is optimized for 3.3-V systems and maintains full functionality-including 5-V input tolerance-within the specified 2.7–3.6 V window. Always refer to the Absolute Maximum Ratings table in the official SN74LVT16240DGGR datasheet for safe design margins.
Does SN74LVT16240DGGR support hot-plug insertion?
Yes, SN74LVT16240DGGR supports hot-plug insertion via two integrated features: Ioff circuitry disables outputs when VCC = 0, preventing backflow current, and power-up 3-state holds outputs in high-impedance during power ramp-up/down. These functions are fully characterized and guaranteed across the –40°C to +85°C temperature range. No external components are required-SN74LVT16240DGGR achieves true hot-swap readiness out-of-the-box.
Can SN74LVT16240DGGR interface directly with 5-V logic?
Yes, SN74LVT16240DGGR accepts input voltages up to 5.5 V while powered from a 3.3-V supply, enabling direct connection to 5-V TTL or CMOS outputs without level-shifting circuitry. This 5-V input tolerance is guaranteed across the full operating temperature range and is a core feature of its ABT process. However, outputs remain 3.3-V referenced and must be received by 3.3-V–compatible inputs unless pulled up externally.
What is the output drive capability of SN74LVT16240DGGR?
SN74LVT16240DGGR provides 64 mA sink current (IOL) and –32 mA source current (IOH) per output at VCC = 3 V, measured under standard load conditions. This drive strength allows reliable interfacing with multiple TTL loads or moderate PCB trace capacitance. The actual drive varies slightly with VCC and temperature-e.g., at VCC = 3.3 V and TA = 25°C, typical IOL is 64 mA and typical IOH is –32 mA, as confirmed in the Electrical Characteristics table of the SN74LVT16240DGGR datasheet.
Is SN74LVT16240DGGR pin-compatible with other 16-bit LVT buffers?
SN74LVT16240DGGR shares identical pinout and function with SN74LVT16240DLR (SSOP-48) and SN74LVT16240DL (SSOP-48 tube), differing only in package type. It is not pin-compatible with non-LVT variants such as SN74LVTH16240 or 74ALVC16240 due to differing OE pin assignments and internal logic mapping. Always verify pin mapping using the "Top View" diagram in the SN74LVT16240DGGR datasheet before board layout reuse.
