Product details
Overview
74ABT16245BDGG,112 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 from 4.5 V to 5.5 V, delivers ±64 mA output drive (LOW), supports -40 °C to +85 °C ambient, and integrates IOFF circuitry for partial power-down protection in hot-swap applications.
For engineers reviewing the 74ABT16245BDGG,112 datasheet, 74ABT16245BDGG,112 pinout, 74ABT16245BDGG,112 application, or 74ABT16245BDGG,112 equivalent, key selection criteria include dual-directional 8-bit partitioning, independent OE/DIR control per bank, TSSOP48 thermal and noise performance, and verified BiCMOS propagation delays under 4 ns.
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-family truth tables: DIR HIGH enables A→B flow; DIR LOW enables B→A flow; OE HIGH forces outputs to high-impedance state.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA, enabling safe partial power-down in multi-rail systems. Static characteristics include VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOL ≤ 0.55 V at 64 mA, and VOH ≥ 2.0 V at -32 mA - all guaranteed across full temperature and supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL and CMOS logic families without level-shifting. |
| Propagation Delay | tPLH/tPHL ≤ 3.5 ns - enables reliable operation in high-speed parallel bus systems up to ~150 MHz clock-equivalent rates. |
| Output Drive | +64 mA / -32 mA - supports driving heavy capacitive loads (e.g., >50 pF) and multiple TTL inputs without signal degradation. |
| IOFF Leakage | ±100 μA at VCC = 0 V - prevents damaging back-current during live insertion or asymmetric power sequencing. |
| Operating Temperature | -40 °C to +85 °C - qualified for industrial-grade environments including factory automation and telecom infrastructure. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 requirements for robust handling and board assembly. |
| Input Clamping Voltage | -1.2 V to -0.9 V - protects inputs against negative transients during hot-swap or cable disconnect events. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH signal selecting data flow direction per bank: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Drives corresponding 8-bit output group into high-impedance state when HIGH; enables normal operation when LOW. |
| 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); connect to master-side bus. |
| 1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23) | Data I/O port B | Secondary bidirectional data terminals for Bank 1 (Pins 2–12) and Bank 2 (Pins 13–23); connect to slave/peripheral bus. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins reduce switching noise and improve power integrity across high-frequency transitions. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, minimizing ground bounce in 16-bit parallel switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit banks | Enables flexible system partitioning: one bank for CPU-to-memory, another for CPU-to-peripheral communication without shared control timing. |
| BiCMOS output stage | Combines bipolar speed (sub-4 ns propagation) with CMOS low static power (<0.7 mA ICC per bank enabled). |
| Power-up 3-state | Outputs remain in high-impedance state until VCC stabilizes, preventing bus contention during power-on reset sequences. |
| Multiple VCC/GND distribution | Reduces simultaneous switching noise by >40 % compared to single-supply-pin alternatives in 16-bit data transfers. |
| Live insertion/extraction support | IOFF + ESD robustness allows safe replacement in powered-backplane systems without system shutdown. |
Applications
| Industrial PLC Backplane Interface | Legacy ISA Bus Extension |

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 | Same ABT logic family, identical pinout and electrical specs; TI version uses different TSSOP48 footprint (SOT362-1 vs. PW-48), minor thermal pad variation. | Valid for drop-in replacement where TI's qualification and documentation are preferred; same industrial temp range and IOFF behavior. | Select if sourcing from TI-authorized channels or requiring TI-specific reliability reporting (e.g., AEC-Q100 not applicable, but TI's internal stress test data). |
| 74LVT16245ADGG,118 | Lower VCC range (2.7–3.6 V), 3.3 V only; 32 mA drive (vs. 64 mA); faster tPLH/tPHL (~2.5 ns typ), but no IOFF circuitry. | Suitable for 3.3 V-only systems with lower drive needs; unsuitable for mixed-voltage or hot-swap applications due to missing IOFF. | Choose only for cost-sensitive 3.3 V designs where partial power-down is not required and drive load ≤ 32 mA. |
Compared with SN74ABT16245DGGR, the 74ABT16245BDGG,112 offers identical functional behavior but differs in manufacturer-specific packaging tolerances and traceability; versus 74LVT16245ADGG,118, it provides higher voltage margin, double output drive, and critical IOFF protection - making it the sole choice for 5 V industrial backplanes with live maintenance.

FAQ
What is the maximum allowable input voltage for 74ABT16245BDGG,112?
The absolute maximum input voltage is -1.2 V to +7.0 V, referenced to GND. However, recommended operating conditions specify VI between 0 V and VCC (4.5–5.5 V). Exceeding VCC by more than 0.5 V risks latch-up unless clamping current remains below -18 mA, as defined in Table 4.
Does 74ABT16245BDGG,112 support hot-swap without external protection?
Yes - its integrated IOFF circuitry disables outputs and limits backflow current to ±100 μA when VCC = 0 V, enabling safe insertion/extraction in powered-backplane systems. No external series resistors or TVS diodes are required for basic hot-swap compliance per JESD78 Class II.
How does the dual OE/DIR architecture improve system timing?
Independent 1OE/2OE and 1DIR/2DIR inputs allow asynchronous control of each 8-bit bank. This eliminates inter-bank timing dependencies, enabling staggered data transfers - e.g., reading status from Bank 1 while writing commands to Bank 2 - reducing overall bus arbitration overhead by up to 30 %.
Can 74ABT16245BDGG,112 interface directly with 3.3 V logic?
No - it is specified only for 4.5–5.5 V operation and has VIH(min) = 2.0 V at VCC = 4.5 V. Driving its inputs from 3.3 V logic may result in marginal HIGH recognition; use a level translator like NXSL1T45 or discrete resistor divider with hysteresis for reliable 3.3 V → 5 V interfacing.
