Product details
Overview
74ABT16245BDGG,512 from Nexperia is a 16-bit 3-state bus transceiver in TSSOP48 package, designed for bidirectional data flow control between two 8-bit or one 16-bit parallel buses. It operates from 4.5 V to 5.5 V, supports -40 °C to +85 °C ambient, delivers ±64 mA output drive, and features dual independent direction (1DIR/2DIR) and output enable (1OE/2OE) controls for flexible bus isolation in industrial backplanes and memory interfaces.
For engineers reviewing the 74ABT16245BDGG,512 datasheet, 74ABT16245BDGG,512 pinout, 74ABT16245BDGG,512 application, or 74ABT16245BDGG,512 equivalent, key selection criteria include its BiCMOS-driven 3.2 ns typical propagation delay, IOFF-enabled partial power-down capability, TTL-compatible input thresholds, and dual 8-bit channel partitioning for segmented bus arbitration.
Technical Context
The device implements two independent 8-bit transceiver channels, each with dedicated direction (DIR) and output enable (OE) inputs, enabling simultaneous or staggered bus control. Its BiCMOS architecture delivers high-speed switching (tPLH/tPHL ≤ 3.5 ns at VCC = 5.0 V) while maintaining TTL-level compatibility and robust noise immunity via multiple VCC/GND pins.
IOFF circuitry actively disables outputs during power-down by clamping leakage to ±100 μA at VCC = 0 V, preventing backflow current. The functional table confirms deterministic behavior: when nOE = HIGH, outputs enter high-impedance state regardless of DIR or data inputs; when nOE = LOW, data flows bidirectionally based on DIR polarity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across industrial-grade 5 V rails with ±10 % tolerance. |
| Propagation Delay | tPLH/tPHL ≤ 3.5 ns - enables sub-300 MHz bus timing margins in high-speed parallel interfaces. |
| Output Drive | +64 mA / -32 mA - drives heavy capacitive loads (e.g., >50 pF) without signal degradation in multi-drop buses. |
| IOFF Leakage | ±100 μA at VCC = 0 V - prevents destructive backfeed current during hot-swap or partial system power-down. |
| Operating Temperature | -40 °C to +85 °C - qualified for extended industrial environments including factory automation and telecom infrastructure. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events without latch-up or parametric shift. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees reliable interfacing with standard TTL and 5 V CMOS logic families. |
Pinout & Package
TSSOP48 package (SOT362-1), 6.1 mm body width, 48-pin thin shrink outline with exposed thermal pad not present; pin 1 index marked, lead pitch 0.5 mm, compliant with JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH signal selecting data flow direction per 8-bit channel (A→B or B→A). |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit outputs; HIGH forces high-impedance OFF-state. |

| 1B0–1B7 (Pins 2,3,5,6,8,9,11,12) | Data I/O port B (Channel 1) | Second 8-bit bidirectional bus interface; connects to peripheral/memory side. |
| 2A0–2A7 (Pins 36,35,33,32,30,29,27,26) | Data I/O port A (Channel 2) | Independent second 8-bit channel for segregated bus domains or redundancy. |
| 2B0–2B7 (Pins 13,14,16,17,19,20,22,23) | Data I/O port B (Channel 2) | Isolated 8-bit path supporting concurrent dual-bus operations. |
| VCC (Pins 7,18,31,42) | Power supply | Four distributed VCC pins minimize IR drop and switching noise across high-current paths. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight GND pins provide low-inductance return paths for fast edge rates and EMI suppression. |
Key Features
| Feature | Design Value |

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 logic function and pinout; TI version uses different BiCMOS process yielding 4.0 ns max tPLH vs. Nexperia's 3.5 ns. | Marginally slower propagation but identical IOFF and drive specs; validated for TI-specific reference designs. | Select when sourcing from TI-authorized channels or requiring TI-design ecosystem alignment. |
| 74LVT16245ADGG,118 | Lower VCC range (2.7–3.6 V); 3.3 V only; 64 mA drive retained but VOL higher (0.55 V vs. 0.42 V at 64 mA). | Designed for mixed-voltage 3.3 V systems; incompatible with 5 V buses without level-shifting. | Choose for cost-sensitive 3.3 V-only applications where 5 V tolerance is unnecessary. |
Compared with SN74ABT16245DGGR, the 74ABT16245BDGG,512 offers tighter propagation delay control for timing-critical 5 V backplanes; versus 74LVT16245ADGG,118, it provides full 5 V compatibility and lower VOL for improved noise margin in legacy industrial systems.

FAQ
Does 74ABT16245BDGG,512 support hot-swap insertion?
Yes. Live insertion/extraction is explicitly permitted per the datasheet. The IOFF circuitry disables outputs when VCC = 0 V, limiting backflow current to ±100 μA and preventing damage during hot-plug events in powered-backplane systems.
What is the maximum capacitive load this transceiver can drive reliably?
The device is characterized up to 50 pF load capacitance in dynamic testing (Table 8). With ±64 mA output drive and 3.5 ns max propagation delay at 50 pF, it reliably drives typical 16-bit bus loads including trace capacitance and 3–5 attached IC inputs without signal integrity degradation.
Can both 8-bit channels operate independently with different direction settings?
Yes. 1DIR and 2DIR are electrically isolated inputs controlling Channels 1 and 2 separately. For example, Channel 1 can transmit A→B while Channel 2 simultaneously transmits B→A, enabling full-duplex 16-bit data exchange across split bus architectures.
How does the power-up 3-state feature prevent bus contention?
At power-on, internal circuitry holds all outputs in high-impedance state until VCC reaches valid operating voltage (≥4.5 V). This eliminates undefined logic states and short-circuit currents that would occur if outputs drove before supply stabilization, protecting connected devices during cold-start sequences.
