Product Overview: Texas Instruments CD54HCT157F3A

The CD54HCT157F3A is a high-speed CMOS Logic Quad 2-Input Multiplexer designed by Texas Instruments, one of the leading manufacturers in the semiconductor industry. This component is part of the HCT (High-Speed CMOS, TTL-Compatible) family, which is known for its compatibility with TTL (Transistor-Transistor Logic) while offering the low power consumption benefits of CMOS technology.

Key Features

• Logic Type: Quad 2-Input Multiplexer
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature: -55°C to 125°C
• Package: Ceramic Flat Pack
• Logic Family: HCT
• Propagation Delay Time: Fast switching times with a typical delay time of 13 ns at 5V
• Output Current: High drive capabilities with 4 mA at the output

Functional Description

The CD54HCT157F3A comprises four identical 2-input multiplexers with common select and enable inputs. Each multiplexer has two data inputs (A and B), one output (Y), one select input (S), and an enable input (E). The select input determines which of the data inputs is connected to the output. When the enable input is high, the multiplexer is disabled, and the output is in the high-impedance state, allowing for use in bus-oriented systems.

Applications

With its versatility and high-speed operation, the CD54HCT157F3A is ideal for a variety of applications, including:

• Data routing
• Signal gating
• Function generation
• Digital signal processing
• Computer systems
