1. Overview The 4B-2054L is a high-efficiency, low-voltage differential driver integrated circuit (IC). It is commonly utilized in industrial automation, motor control systems, and digital communication buses requiring robust signal transmission over long cable runs or noisy environments.
| Input | Enable (Pin12) | Enable' (Pin8) | A Output | Y Output | |-------|----------------|----------------|----------|----------| | H | H | H | H | L | | L | H | H | L | H | | X | L | X | High-Z | High-Z | | X | X | L | High-Z | High-Z | 4b-2054l driver
Pins 3 & 13 are both GND; Pins A/Y denote differential output pairs (A = +, Y = –). 4. Functional Block Diagram The 4B-2054L contains four independent differential line drivers. Each driver converts a single-ended TTL/CMOS input into a balanced differential output (A and Y). The two enable pins (Pin 8: active-low, Pin 12: active-high) control all four drivers simultaneously for bus-oriented applications. | Input | Enable (Pin12) | Enable' (Pin8)
