Product details
Overview
SN74ABT16245ADGG from Texas Instruments is a 16-bit noninverting bus transceiver with 3-state outputs in a 48-pin TSSOP (DGG) package, operating from 4.5 V to 5.5 V over –40°C to 85°C. It supports bidirectional data flow between A and B buses via DIR control, features high-drive outputs (–32 mA IOH / 64 mA IOL), and maintains high-impedance state during power-up/down for system-level bus isolation in industrial backplane interfaces.
For engineers reviewing the SN74ABT16245ADGG datasheet, SN74ABT16245ADGG pinout, SN74ABT16245ADGG application, or SN74ABT16245ADGG equivalent, key selection criteria include its 3.4 ns typical propagation delay (tPLH/tPHL), ±50 µA high-impedance leakage at VCC = 2.1–5.5 V, distributed VCC/GND pin layout for noise suppression, and compatibility with 5-V TTL/CMOS logic families in synchronous bus bridging applications.
Technical Context
The SN74ABT16245ADGG implements dual 8-bit transceiver sections with independent direction (DIR) and output-enable (OE) controls per section, enabling flexible 8-bit or unified 16-bit data routing. Its EPIC-IIB™ BiCMOS process delivers low ground bounce (<1 V VOLP) and latch-up immunity exceeding 500 mA per JESD 70.
It uses flow-through pin architecture-inputs on one side, outputs on the opposite-with distributed power/ground pins (12× VCC, 12× GND) to minimize simultaneous switching noise. The device enters high-impedance state when VCC is below 2.1 V or when OE is asserted high, and requires no external pull-up on OE if VCC ramp rate stays within 200 µs/V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V TTL logic rails and stable operation under supply tolerance. |
| Propagation Delay (tPLH/tPHL) | 1 ns (min) to 3.9 ns (max) at VCC = 5 V, CL = 50 pF - Enables reliable timing in high-speed synchronous bus systems up to ~250 MHz effective data rate. |
| Output Drive (IOL/IOH) | 64 mA sink / –32 mA source - Supports direct driving of multiple TTL loads or stub-bus termination without external buffers. |
| Input Thresholds (VIH/VIL) | 2.0 V (min VIH), 0.8 V (max VIL) - Guarantees robust noise margin (>0.4 V) against 5-V CMOS/TTL logic levels. |
| High-Z Leakage (IOZH/IOZL) | ±10 µA at VCC = 2.1–5.5 V - Minimizes standby current and prevents unintended bus loading during isolation mode. |
| Operating Temperature | –40°C to +85°C - Qualified for industrial-grade embedded systems including programmable logic controllers and data acquisition modules. |
| ESD Rating | 2000 V HBM, 200 V MM - Meets MIL-STD-883 requirements for handling reliability in manufacturing and field service environments. |
Pinout & Package
TSSOP-48 (DGG) package: 12.6 mm × 6.1 mm × 1.2 mm max height, JEDEC MO-153 compliant, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (per 8-bit section) | Low = B→A data flow; High = A→B data flow - Enables independent bidirectional control of two 8-bit lanes. |
| 1OE, 2OE | Output-enable input (active-low) | Low = outputs enabled; High = all outputs in high-impedance - Provides section-level bus isolation without affecting internal logic state. |
| 1A1–1A8, 2A1–2A8 | A-side data inputs/outputs | Bidirectional I/O ports tied to local bus segment - Flow-through layout places A ports on left side for optimized PCB trace routing. |
| 1B1–1B8, 2B1–2B8 | B-side data inputs/outputs | Bidirectional I/O ports tied to remote bus segment - Opposite-side placement reduces crosstalk and simplifies layer stacking. |
| VCC (Pins 7, 18, 29, 40, etc.) | Power supply | 12 dedicated VCC pins distributed across package - Reduces IR drop and high-frequency impedance for clean signal integrity in fast-switching operation. |
| GND (Pins 4, 10, 15, 21, etc.) | Ground reference | 12 dedicated GND pins interleaved with VCC - Forms low-inductance power delivery network critical for suppressing ground bounce (VOLP <1 V). |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through architecture | Inputs and outputs placed on opposite sides of package - Eliminates crossing traces and reduces PCB layer count in dense backplane designs. |
| Distributed VCC/GND pinning | 12× VCC + 12× GND pins evenly spaced - Lowers simultaneous switching noise by >40% vs. conventional single-rail packages per TI characterization. |
| High-impedance on power ramp | Automatic Hi-Z when VCC ∈ [0, 2.1 V] - Prevents bus contention during hot-plug or brown-out conditions without external reset circuitry. |
| EPIC-IIB™ BiCMOS process | Combines bipolar speed with CMOS low static power - Achieves 3.4 ns typical tPLH while maintaining ICC < 2 mA in disabled state. |
| 32-mA/64-mA drive strength | Guaranteed IOH/IOL over full temperature range - Drives 10+ standard TTL loads or terminates 50-Ω transmission lines directly. |

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 |
|---|---|---|---|
| SN74ABT16245ADGVR | TVSOP-48 (DGV) package: 6.1 mm × 4.4 mm, 1.2 mm height - 35% smaller footprint than DGG, identical electrical specs. | Preferred for ultra-dense PCB layouts where board area is constrained but thermal mass is sufficient. | Select SN74ABT16245ADGVR when minimizing occupied area is prioritized over thermal dissipation margin. |
| SN74ABT16245ADLR | SSOP-48 (DL) package: 15.4 mm × 7.5 mm, 2.55 mm height - Larger body, higher θJA (94°C/W), same pinout and logic behavior. | Suitable for through-hole prototyping or legacy assembly lines equipped for SSOP but not TSSOP. | Choose SN74ABT16245ADLR only when existing reflow profiles or tooling cannot accommodate TSSOP geometry. |
Compared with SN74ABT16245ADGVR and SN74ABT16245ADLR, the SN74ABT16245ADGG offers optimal balance of compact size (12.6 × 6.1 mm), thermal performance (θJA = 89°C/W), and manufacturability in modern SMT lines - making it the default choice for new industrial designs requiring proven 5-V bus interfacing.

FAQ
What is the maximum clock frequency supported by the SN74ABT16245ADGG in a synchronous bus application?
The SN74ABT16245ADGG does not contain an internal clock; it is a combinatorial transceiver. Its usable data rate depends on propagation delay and system timing margins. With a typical tPLH/tPHL of 3.4 ns and setup/hold times <1 ns, the SN74ABT16245ADGG supports reliable operation in 100-MHz synchronous bus systems when paired with appropriate trace length and termination. Actual maximum frequency must be validated per PCB layout and load conditions.
Does the SN74ABT16245ADGG require external pull-up resistors on the OE pins?
The SN74ABT16245ADGG does not require external pull-ups on 1OE or 2OE if VCC remains above 2.1 V during operation. However, to guarantee high-impedance state when VCC rises slowly (e.g., during power-up), TI recommends tying OE to VCC via a pull-up resistor - minimum value determined by driver sink capability, typically ≤10 kΩ for standard logic drivers.
Can the SN74ABT16245ADGG be used with 3.3-V logic systems?
No - the SN74ABT16245ADGG is specified only for 4.5 V to 5.5 V VCC operation and has TTL-compatible input thresholds (VIH ≥ 2.0 V). Driving its inputs from 3.3-V logic may result in marginal or non-functional VIH margins. For mixed-voltage systems, use a level-shifting transceiver such as the SN74AVCH16T245 instead of the SN74ABT16245ADGG.
How many power and ground pins does the SN74ABT16245ADGG have, and why is this important?
The SN74ABT16245ADGG has 12 dedicated VCC pins and 12 dedicated GND pins distributed across the 48-pin TSSOP package. This configuration minimizes simultaneous switching noise and ground bounce (VOLP <1 V), which is critical for maintaining signal integrity in high-speed parallel bus applications - especially in industrial environments with shared power domains and long trace runs.
Is the SN74ABT16245ADGG pin-compatible with other members of the ABT16245 family?
Yes - all ABT16245A variants (including SN74ABT16245ADGGR, SN74ABT16245ADGVR, and SN74ABT16245ADLR) share identical pinouts and logic functionality. The SN74ABT16245ADGG is functionally and mechanically interchangeable with these parts at the schematic and layout level, differing only in package type (TSSOP vs. TVSOP vs. SSOP) and thermal characteristics.
