TC74LCX245FK(EL,K)** is a low-voltage CMOS octal bus transceiver manufactured by **Toshiba**.

The TC74LCX245FK(EL,K) is a low-voltage CMOS octal bus transceiver manufactured by Toshiba. Below are its key specifications, descriptions, and features:

Specifications:

  • Logic Family: LCX (Low-Voltage CMOS)
  • Number of Bits: 8 (Octal)
  • Supply Voltage Range: 2.0V to 3.6V
  • High-Speed Operation: tpd = 4.5ns (max) at 3.3V
  • Low Power Consumption: ICC = 10μA (max) at Ta = 25°C
  • Input/Output Tolerance: 5V-tolerant inputs and outputs
  • Output Drive Capability: ±24mA at 3.0V
  • Direction Control: DIR pin for bidirectional data flow
  • Output Enable: OE (active low) for tri-state outputs
  • Package Type: SSOP20 (20-pin Shrink Small Outline Package)
  • Operating Temperature Range: -40°C to +85°C

Descriptions:

The TC74LCX245FK(EL,K) is a bidirectional octal bus transceiver designed for low-voltage (2.0V–3.6V) applications. It features non-inverting data paths and is controlled by a Direction (DIR) pin and an Output Enable (OE) pin. When OE is low, the device allows data transmission based on the DIR pin (high for A→B, low for B→A). When OE is high, the outputs are in a high-impedance state.

Features:

  • 5V-tolerant inputs and outputs for mixed-voltage applications
  • Low-voltage operation (2.0V–3.6V)
  • High-speed performance (4.5ns max propagation delay)
  • Bidirectional data flow with direction control
  • Tri-state outputs for bus isolation
  • Low power consumption (ideal for battery-operated devices)
  • ESD protection (Human Body Model ≥ 2000V)

This device is commonly used in data communication systems, networking equipment, and portable electronics where low-voltage, high-speed bidirectional data transfer is required.
