Product details
Overview
8V16245AMDLREPG4 from Texas Instruments is a 3.3-V ABT 16-bit dual-octal noninverting bus transceiver with 3-state outputs, designed for mixed-mode signal operation (5-V inputs/outputs with 3.3-V VCC), hot-insertion support via Ioff and power-up 3-state, and bus-hold on all data inputs. It operates across –55°C to 125°C and is used in high-reliability aerospace and defense interconnect systems requiring TTL-level compatibility and robust isolation.
For engineers reviewing the 8V16245AMDLREPG4 datasheet, 8V16245AMDLREPG4 pinout, 8V16245AMDLREPG4 application, or 8V16245AMDLREPG4 equivalent, key selection criteria include its –55°C to 125°C extended temperature rating, SSOP-48 package with distributed VCC/GND pins for noise reduction, flow-through architecture for optimized PCB layout, and guaranteed 24-mA low-level output drive at VCC = 2.7 V.
Technical Context
The 8V16245AMDLREPG4 implements a dual-octal transceiver architecture with independent direction-control (1DIR/2DIR) and output-enable (1OE/2OE) inputs per 8-bit section, enabling bidirectional data flow between A and B buses. Its ABT BiCMOS process delivers low static power dissipation while supporting 5-V-tolerant I/Os at 3.3-V supply.
It features active bus-hold circuitry eliminating external pullup/pulldown resistors, Ioff protection preventing backflow during power-down, and power-up 3-state ensuring high-impedance outputs during VCC ramp. Absolute maximum ratings include VI up to 7 V and VO up to VCC + 0.5 V in high state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V without functional degradation |
| IOH / IOL | –24 mA / 24 mA at VCC = 2.7 V - sufficient drive strength for TTL loads under worst-case low-voltage conditions |
| tPLH / tPHL | 4.5 ns / 4.4 ns max at VCC = 2.7 V - ensures timing compliance in high-speed 16-bit parallel bus applications |
| VIH / VIL | 2.0 V / 0.8 V - compatible with standard TTL logic thresholds for seamless 5-V system interfacing |
| Operating Temp | –55°C to 125°C - qualified for extended-temperature military and space-grade embedded systems |
| Bus-Hold Current | ±750 µA max - actively maintains valid logic states on undriven A/B port inputs without external components |
| Ioff Leakage | ±100 µA max at VI/VO = 0 to 4.5 V - prevents damaging current flow during hot-swap or partial power-down |
Pinout & Package
8V16245AMDLREPG4 is housed in a 48-pin SSOP (DL) package with 0.5-mm pitch, 12.6 mm × 6.2 mm body size, and 1.2-mm max height. Pin 1 identifier is located in quadrant Q1 of the tape reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Determines data flow direction per 8-bit section: L = B→A, H = A→B |
| 1OE, 2OE | Output enable input | Active-low control: L enables outputs, H places both A and B ports in high-impedance state |
| 1A1–1A8, 2A1–2A8 | Port A data inputs/outputs | First and second 8-bit data channels on A side; bus-hold enabled |
| 1B1–1B8, 2B1–2B8 | Port B data inputs/outputs | First and second 8-bit data channels on B side; bus-hold enabled |
| VCC (Pins 7, 16, 24, 33, 41) | Supply voltage | Distributed VCC pins minimize simultaneous switching noise and improve power integrity |
| GND (Pins 4, 10, 19, 27, 36, 44) | Ground reference | Multiple GND pins reduce ground bounce and enhance signal integrity at high speed |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode I/O tolerance | 5-V input/output capability with 3.3-V VCC enables direct interface to legacy 5-V logic without level shifters |
| Hot-insertion support | Ioff and power-up 3-state prevent backflow and bus conflicts during live board insertion or removal |
| Flow-through pinout | A/B port signals arranged linearly (e.g., 1A1–1A8 adjacent to 1B1–1B8) simplifies layer routing and reduces trace crossovers |
| Bus-hold circuitry | Eliminates need for external pullup/pulldown resistors on all 32 data lines, reducing BOM count and board area |
| Distributed power/ground | Five VCC and six GND pins evenly spaced across package suppress high-frequency switching noise and EMI |
Applications

FAQ
What is the operating temperature range specified for the 8V16245AMDLREPG4?
The 8V16245AMDLREPG4 is fully specified for operation from –55°C to 125°C. This extended temperature range is validated per JEDEC and industry standards including biased 85/85 testing, temperature cycling, and HAST, making it suitable for deployment in space-grade and military environmental conditions where standard commercial or industrial grade parts would fail.
Does the 8V16245AMDLREPG4 support hot-plug or hot-insertion functionality?
Yes, the 8V16245AMDLREPG4 supports hot-insertion via two integrated features: Ioff circuitry disables outputs during power-down to prevent damaging current backflow, and power-up 3-state forces outputs into high-impedance during VCC ramp. These functions are fully characterized and guaranteed across the –55°C to 125°C range, enabling safe live insertion into powered backplanes.
How does the bus-hold feature of the 8V16245AMDLREPG4 eliminate the need for external resistors?
The 8V16245AMDLREPG4 integrates active bus-hold circuitry on all 32 A/B port inputs, maintaining undriven or floating lines at valid logic states with ±750 µA dynamic hold current. This eliminates external pullup/pulldown resistors, reducing BOM cost, PCB area, and potential signal integrity issues caused by resistor parasitics-verified per datasheet Section 6.4.
What package type and pin count does the 8V16245AMDLREPG4 use?
The 8V16245AMDLREPG4 uses a 48-pin SSOP (DL) package with 0.5-mm pitch, 12.6 mm × 6.2 mm body dimensions, and 1.2-mm maximum height. Pin 1 is located in quadrant Q1 per tape-and-reel packaging specifications, and the package conforms to JEDEC MO-153 mechanical standards.
Is the 8V16245AMDLREPG4 pin-compatible with other variants in the SN74LVTH16245A family?
Yes, the 8V16245AMDLREPG4 shares identical pinout, footprint, and function mapping with all DL-package variants including SN74LVTH16245AQDLREP and SN74LVTH16245AMDLREP. All DL-packaged versions use the same terminal assignments, flow-through architecture, and control signal locations-confirmed in TI's SCAS693G datasheet Figure 1 and Package Option Addendum.
