MC74ACT153D

Overview

The MC74ACT153D is a dual 4-input multiplexer in a 16-lead SOIC package. It features TTL-compatible inputs and outputs capable of sourcing or sinking 24 mA. The device operates at a supply voltage (VCC) of 4.5 V to 5.5 V. Propagation delays range from 5.5 ns to 13.5 ns depending on the input path and load conditions.

Feature Summary

• Dual independent 4-input multiplexing sections with common select lines
• TTL-compatible logic levels for direct interface with standard digital systems
• High-current buffered outputs providing robust drive capability

Applications

• Data routing and selection between multiple sources
• Implementation of combinational logic functions
• Parallel-to-serial data conversion circuits

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the 'D' suffix designates the SOIC-16 form factor. Confirm lead-free compliance status and check for any recent product change notifications regarding material composition or manufacturing site updates before finalizing procurement orders.

Selection Notes

Select this component when TTL-level compatibility is required alongside high-speed switching capabilities. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the output current requirements do not exceed the 24 mA limit per pin to maintain signal integrity and device reliability.

Part Context

This device belongs to the MC74ACT series of high-speed CMOS logic components manufactured by onsemi. It provides a dual multiplexer function within a standard 16-pin surface-mount footprint, serving as a bridge between legacy TTL logic standards and modern CMOS performance characteristics.

FAQ

How are the enable inputs configured?

The Enable inputs (Ea, Eb) are active-LOW. When driven HIGH, the corresponding outputs are forced LOW regardless of the select or data inputs.

What is the maximum quiescent supply current?

The maximum quiescent supply current (ICC) is guaranteed to be 80 µA at 5.5 V with all inputs tied to VCC or GND.
