Product details
Overview
SN74ABT16540ADGVR from Texas Instruments is an inverting 16-bit bus buffer/driver with dual 3-state output-enable control, designed for high-speed wide-data-path interfacing in industrial and telecom backplanes. It delivers –32-mA high-level and 64-mA low-level output drive, operates from 4.5 V to 5.5 V, and is rated for –40°C to 85°C ambient temperature.
For engineers reviewing the SN74ABT16540ADGVR datasheet, SN74ABT16540ADGVR pinout, SN74ABT16540ADGVR application, or SN74ABT16540ADGVR equivalent, key selection criteria include its flow-through architecture for PCB layout optimization, distributed VCC/GND pinning to suppress switching noise, latch-up immunity >500 mA per JESD-17, and guaranteed 3-state timing (tPZH/tPZL ≤ 5.2 ns at VCC = 5 V).
Technical Context
This device implements two independent 8-bit inverting buffer sections, each with a 2-input AND-gated 3-state control (active-low OE1/OE2). A high on either OE input forces all corresponding outputs into high-impedance, enabling robust bus arbitration. The EPIC-IIB BiCMOS process enables low ground bounce (VOLP < 1 V) and reduced power dissipation versus legacy TTL.
Its flow-through pinout-inputs on one side, outputs on the opposite-minimizes trace crossovers. Distributed power/ground pins (12× GND, 6× VCC) and tight 0.5-mm pitch in the TSSOP-48 package support stable operation at >100 MHz data rates under heavy capacitive loading (CL = 50 pF).
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 |
|---|---|---|---|
| SN74ABT16541ADGVR | Non-inverting logic function; identical pinout, drive strength, and timing specs | Required where bus polarity must be preserved (e.g., direct replacement in non-inverting data paths) | Select when system logic requires true (non-inverted) signal replication without external inversion |
| SN74LVC16244ADGVR | Lower voltage (1.65–3.6 V), CMOS-only process; 24-mA drive, higher propagation delay (6.7 ns) | Suitable only for 3.3-V systems; lacks latch-up immunity and high-noise immunity of ABT family | Choose for cost-sensitive, low-power 3.3-V applications where 5-V tolerance and industrial temp range are not required |
Compared with SN74ABT16540ADGVR, SN74ABT16541ADGVR preserves signal polarity but shares identical packaging, drive, and timing-making it a functional alternative where inversion is undesirable. SN74LVC16244ADGVR reduces power and cost in 3.3-V designs but sacrifices 5-V compatibility, noise margin, and industrial temperature support.

FAQ
What is the logic function of the SN74ABT16540ADGVR?
The SN74ABT16540ADGVR is an inverting 16-bit buffer/driver with dual 3-state output-enable control. Each of its two 8-bit sections performs logical inversion (Y = NOT A) and enters high-impedance when either OE1 or OE2 is high. This behavior is confirmed in the device's function table and logic diagram in the official SCBS208C datasheet.
Does the SN74ABT16540ADGVR support 5-V operation?
Yes, the SN74ABT16540ADGVR is fully specified for 4.5 V to 5.5 V supply operation per its recommended operating conditions. It interfaces natively with 5-V TTL and LVTTL systems, and its absolute maximum VCC rating is 7 V, providing margin against supply transients.
What package type is used for the SN74ABT16540ADGVR?
The SN74ABT16540ADGVR uses the TSSOP-48 (DGVR) package: 48-pin, 0.5-mm pitch, 12.5 mm × 6.1 mm body size, 1.2-mm maximum height, with NIPDAU lead finish and JEDEC MSL Level-1 rating for unlimited floor life at ≤30°C/60% RH.
How does the 3-state enable logic work on the SN74ABT16540ADGVR?
The SN74ABT16540ADGVR uses a 2-input AND gate per section for 3-state control: both OE1 and OE2 must be low to enable outputs; if either is high, all eight outputs go high-impedance. This is explicitly defined in the function table and logic diagram of the SCBS208C datasheet.
Is the SN74ABT16540ADGVR suitable for industrial temperature applications?
Yes, the SN74ABT16540ADGVR is characterized for operation from –40°C to +85°C, meeting industrial temperature grade requirements. Its latch-up immunity (>500 mA per JESD-17) and low ground bounce (<1 V) further validate its suitability for harsh industrial environments.
