The MM74HCT153N is a high-speed CMOS logic device featuring a dual 4-input multiplexer. It is part of the 74HCT family, offering TTL-compatible input thresholds while maintaining the advantages of CMOS technology, such as low power consumption and high noise immunity. This multiplexer allows selection of one of four data sources per section based on the select inputs.

Applications:

• Data routing
• Logic function generation
• Parallel-to-serial conversion
• Digital switching
• Address decoding

Features:

• TTL Input Compatible
• High Speed Operation: tpd = 17 ns (typ.) at VCC = 5V
• Low Power Dissipation: ICC = 4 μA (max.) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 30 % VCC (min.)
• Output Drive Capability: 10 LSTTL Loads
• Symmetrical Output Impedance: |IOH| = IOL = 4 mA (min.)
• Balanced Propagation Delays: tPLH ≈ tPHL
• Wide Operating Voltage Range: VCC = 4.5V to 5.5V

Benefits:

• Easy interface with TTL devices.
• Increased system speed due to high-speed operation.
• Reduced power consumption, making it suitable for power-sensitive applications.
• Improved noise immunity for reliable operation.
• Direct compatibility with LSTTL devices simplifies system integration.
• Simplified design due to balanced propagation delays.

Additional Details:

The MM74HCT153N contains two identical 4-input multiplexers. Each multiplexer has four data inputs (I0-I3), two select inputs (S0, S1), an enable input (E), and an output (Y). The select inputs determine which of the four data inputs is routed to the output. The enable input is active-LOW; when it is high, the output is forced to a low state. The device is supplied in a 16-lead DIP package.

Technical Specifications:

• Supply Voltage: 4.5V to 5.5V
