The TC74ACT157P is a high-speed quad 2-input multiplexer from Toshiba Semiconductor and Storage, belonging to the Advanced CMOS Technology (ACT) logic family. This device operates with a supply voltage of 4.5V to 5.5V. It selects one of two 4-bit data sources as a function of the common Select input. The four buffered outputs present the selected data in the true (non-inverted) form. The EN input, when HIGH, forces all outputs LOW. It's used where data needs to be routed from multiple sources to a single destination.

Applications:

• Data selection and routing
• Parallel-to-serial conversion
• Address decoding
• Logic function generation
• Memory address multiplexing

Features:

• High-speed operation: tpd = 5.5 ns (typ.) at VCC = 5V
• Low power consumption: ICC = 4 μA (max.) at VCC = 5V
• TTL compatible inputs
• Enable input for output control
• Symmetrical output drive: |IOH| = IOL = 24 mA
• Wide operating temperature range: -40°C to +85°C
• Package: DIP16 (Dual In-line Package)

Benefits:

• Fast data selection for high-performance systems
• Low power consumption contributes to energy efficiency
• Easy integration with TTL logic circuits
• Output control for bus management
• Directly drives LEDs and other high-current loads
• Suitable for diverse application environments
• Through-hole mounting for robust connections

Additional Details:

The TC74ACT157P is fabricated using silicon gate CMOS technology. The device's inputs are equipped with clamp diodes. The 'P' suffix indicates a DIP (Dual In-Line Package) for through-hole mounting. This device is commonly used in microprocessor systems, memory controllers, and other digital logic applications where efficient data selection is required. The enable input allows for easy cascading of multiple multiplexers to handle larger data widths. It is pin-compatible with standard TTL/CMOS multiplexers.
