Product details
Overview
74ABT16245BDGG,118 from Nexperia is a 16-bit bidirectional bus transceiver with dual 3-state control, designed for high-speed TTL-level data bus interfacing in industrial and embedded systems. It operates at 4.5–5.5 V, delivers ±64 mA output drive, supports partial power-down via IOFF, and functions across –40 °C to +85 °C. Used in memory expansion, microprocessor bus buffering, and backplane interface applications.
For engineers reviewing the 74ABT16245BDGG,118 datasheet, 74ABT16245BDGG,118 pinout, 74ABT16245BDGG,118 application, or 74ABT16245BDGG,118 equivalent, key selection criteria include bidirectional 16-bit data flow control, independent OE/DIR per 8-bit bank, IOFF-enabled hot-swap capability, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
The device implements two independent 8-bit transceiver banks (Bank 1: A0–A7/B0–B7; Bank 2: A0–A7/B0–B7), each with dedicated direction (1DIR/2DIR) and output enable (1OE/2OE) inputs. Logic operation follows standard ABT-series TTL-compatible thresholds: VIH ≥ 2.0 V, VIL ≤ 0.8 V.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA, enabling safe live insertion/extraction. Propagation delays are tightly controlled: tPLH/tPHL ≤ 3.5 ns (max), tPZH/tPLZ ≤ 5.1 ns (max) at VCC = 5.0 V, supporting >200 MHz bus timing margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures robust operation under industrial rail tolerances and brown-out immunity. |
| Output Drive | +64 mA / –32 mA - Supports heavy capacitive loads (e.g., 50 pF buses) and drives multiple TTL inputs without external buffers. |
| Propagation Delay | ≤ 3.5 ns (tPLH/tPHL) - Enables reliable 200+ MHz data transfer on synchronous parallel buses. |
| IOFF Leakage | ±100 μA at VCC = 0 V - Prevents damaging back-current during hot-swap or partial power-down sequences. |
| Operating Temperature | –40 °C to +85 °C - Qualified for extended industrial environments without derating. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces field failure risk in handling and assembly. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Guarantees clean logic recognition with standard 5 V TTL and CMOS sources. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, surface-mount compatible with automated reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH signal selecting data flow direction per 8-bit bank (A→B or B→A). |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit bank outputs; HIGH forces high-impedance state. |
| 1A0–1A7, 2A0–2A7 (Pins 37–47, 26–36) | Data I/O port A | Primary bidirectional data terminals for Bank 1 (Pins 37–47) and Bank 2 (Pins 26–36). |
| 1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23) | Data I/O port B | Secondary bidirectional data terminals paired with Port A for full 16-bit transceiver operation. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins reduce switching noise and improve power integrity across high-speed operation. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, critical for signal integrity and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit banks | Enables flexible system partitioning - e.g., one bank for address bus, another for data bus - without inter-bank timing coupling. |
| IOFF partial power-down | Permits safe hot-plug operation and system-level power sequencing where VCC may be ramped independently across subsystems. |
| BiCMOS output stage | Delivers TTL-compatible voltage levels and high sink current (+64 mA) while maintaining fast edge rates (<3.5 ns). |
| Power-up 3-state | Outputs remain in high-impedance until VCC stabilizes, preventing bus contention during power-on reset sequences. |
| Multiple VCC/GND pins | Reduces simultaneous switching noise (SSN) by distributing supply/return paths - essential for stable 16-bit parallel bus signaling. |
Applications
| Memory Expansion Interface | Microprocessor Bus Buffering |
|---|---|
|
Use Scenario: Extending 16-bit data/address bus between CPU and off-chip SRAM or Flash memory in industrial controllers. IC Role / Device Role / Timing Role: Bidirectional bus transceiver isolating CPU core from memory load; direction controlled by CPU's RD/WR signals. Use Value: Enables clean signal integrity over longer traces, supports 200+ MHz burst transfers, and prevents bus contention during memory access arbitration. |
Use Scenario: Isolating and driving shared data bus between multiple peripherals (UART, SPI controller, GPIO expander) and host MCU. IC Role / Device Role / Timing Role: Level-shifting and bus-driving transceiver; OE controlled by peripheral select logic, DIR synchronized with data transfer direction. Use Value: Eliminates need for discrete buffers; IOFF allows safe peripheral hot-swap without resetting MCU or disrupting other bus segments. |
| Backplane Data Interconnect | Legacy ISA/PCI Bus Bridge |
|
Use Scenario: High-reliability data routing across modular backplane in test equipment or programmable logic racks. IC Role / Device Role / Timing Role: 16-bit bidirectional repeater with independent bank enables; used in master-slave slot communication protocols. Use Value: Maintains signal fidelity over 10+ cm backplane traces; dual OE permits time-multiplexed use of same physical bus by multiple modules. |
Use Scenario: Adapting modern FPGA-based controllers to legacy ISA or PCI bus standards requiring 5 V tolerant, high-drive transceivers. IC Role / Device Role / Timing Role: Protocol-transparent bus interface translating between internal FPGA logic levels and external 5 V bus signaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16245DGGR (TI) | Identical logic function, pinout, and DC specs; differs in thermal resistance (θJA = 52 °C/W vs. Nexperia's 60 °C/W) and packaging (TSSOP48, same SOT362-1 footprint). | Validated in TI-specific reference designs for DSP and FPGA carrier boards; identical timing but slightly better thermal performance. | Select for TI ecosystem alignment or if board layout uses TI-recommended thermal pad design rules. |
| 74LVT16245ADGG,118 (Nexperia) | Lower VCC range (2.7–3.6 V), reduced drive (±32 mA), faster propagation (≤2.5 ns), no IOFF - not suitable for 5 V or hot-swap use. | Targeted for 3.3 V LVTTL systems only; lacks partial power-down, making it unsuitable for mixed-rail or hot-plug applications. | Choose only for pure 3.3 V designs requiring lower power and higher speed - not a drop-in replacement for 5 V or IOFF-critical use cases. |
Compared with SN74ABT16245DGGR, the 74ABT16245BDGG,118 offers marginally higher thermal resistance but identical functional behavior and qualification; versus 74LVT16245ADGG,118, it provides full 5 V compatibility, IOFF safety, and double the sink current - essential for legacy and industrial bus interfaces.

FAQ
Does the 74ABT16245BDGG,118 support hot-swap insertion?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA. This prevents damage during live insertion/extraction in powered-backplane systems. The device meets JESD78 Class II Level B latch-up immunity (>500 mA), further ensuring robustness in hot-swap scenarios.
What is the maximum clock/data rate supported by this transceiver?
The device does not operate on a clock; it is asynchronous. However, its propagation delays (tPLH/tPHL ≤ 3.5 ns max at VCC = 5.0 V) support reliable data transfer on parallel buses up to 200+ MHz, assuming proper PCB layout, termination, and load capacitance ≤50 pF per line.
Can both 8-bit banks be used simultaneously as a single 16-bit transceiver?
Yes. Pins 1DIR/2DIR and 1OE/2OE can be tied together respectively to configure the device as a unified 16-bit transceiver. The functional diagram and truth table confirm identical behavior across both banks, enabling seamless co-use with matched timing and drive capability.
Is the 74ABT16245BDGG,118 automotive qualified?
No. This part is specified for industrial temperature range (–40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in automotive applications requires separate validation and carries no manufacturer warranty or liability coverage.
