SNJ54LVTH162245WD

SNJ54LVTH162245WD is TI’s military-grade (SNJ) 16-bit bidirectional bus transceiver with 3-state outputs in a WD package. It contains two 8-bit transceivers (A0–A15 and B0–B15) and uses a direction input (DIR) and an output-enable input (OE) to shuttle data between the two buses. When OE is active, data can flow in the selected direction (A→B when DIR=0, B→A when DIR=1); when OE is disabled, both sides go high-impedance for bus sharing. It’s built in low-voltage CMOS (LVTH) logic, typically operating from a 4.5–5.5 V supply, with CMOS/TTL-compatible inputs. Applications include buffering or interfacing two buses, memory and I/O expansion, or level/voltage-bridging in mixed-signal systems. Package WD denotes a specific SMD package, usually 20 pins. See SN74LVTH162245 as a non-military alternative with similar function.

Key features of SNJ54LVTH162245WD (16-bit bidirectional bus transceiver):
- 16-bit device (two 8-bit sections) with 3-state outputs
- Bidirectional data path: DIR controls A↔B data flow
- Output enable (OE) to put outputs in high-impedance state
- Non-inverting, low-voltage CMOS/CMOS-compatible inputs
- Wide-voltage operation: typically 3.3 V to 5.5 V
- High-drive capability suitable for bus interconnections
- Fast propagation/transition times (LVTH family: high-speed CMOS)
- Low power consumption
- Temperature grade: automotive/industrial (extended range, e.g., -55°C to 125°C)
- Useful for bus expansion, backplane/interfacing microprocessors with other logic
Applications include microprocessor/microcontroller bus interfacing, backplane wiring, and data-path isolation where bidirectional 8-bit bus pairs are needed.

- Pin count: 20 pins (in the standard SNJ LVTH162245 WD package).
- Function: 16-bit bidirectional bus transceiver with tri-state outputs. It maps A0–A7 to B0–B7 (and vice versa) under control of DIR; two output-enable controls (depending on package, typically 1OE and/or 2OE) tri-state the outputs. This allows data to pass in either direction on a shared bus with proper enable control.

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other semiconductor products.

SNJ54LVTH162245WD is a 16-bit bidirectional bus transceiver with 3-state outputs (LVTTL-compatible). Typical applications:
- Data/address bus buffering for microprocessors, microcontrollers, and DSPs
- 16-bit bus expansion to memory, peripherals, or FPGAs
- Bidirectional level shifting between different voltage domains (mixed-voltage systems)
- Bus isolation and tri-state buffering to prevent contention on shared data buses
- Interface and buffering in system test/debug setups and rapid prototyping
These use cases leverage its DIR and OE control to manage data flow and bus enablement.
