Introduction
SN74LVC8T245RHLR
The SN74LVC8T245RHLR is an 8-bit bidirectional bus transceiver manufactured by Texas Instruments (TI), belonging to the LVC (Low-Voltage CMOS) logic family. Optimized for low-power, wide-voltage operation, it enables seamless bidirectional data transmission between different voltage domains. This integrated 8-channel solution is essential for cross-voltage-domain data exchange, bus expansion, and signal isolation in compact, power-constrained electronic systems.
Core Functional Characteristics
- Bidirectional Data Transmission: Enables two-way data flow between two independent bus ports (A port: A1-A8; B port: B1-B8). Direction is controlled by a single direction pin (DIR).
- Cross-Voltage-Domain Compatibility: Supports wide voltage ranges (1.65V to 5.5V) for both ports, allowing seamless data exchange between systems with different voltage rails.
- High-Drive Strength & Signal Integrity: Delivers ±24mA output drive current at 3.3V with low on-resistance (≤8Ω) for stable data transmission.
- Bus Isolation via Output Enable: Features an active-low output enable pin (OE) for isolating connected buses to prevent signal collision.
