74AC253SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74AC253SCX is a dual 4-input multiplexer with 3-STATE outputs housed in a 16-SOIC package. It selects two bits of data from four sources using common select inputs (S0, S1). The device operates on a single power supply ranging from 2V to 6V and supports an operating temperature range of -40°C to +85°C. Outputs can individually switch to a high impedance state via respective Output Enable (OE) inputs, facilitating direct interfacing with bus-oriented systems.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexing capability with common select inputs
• Non-inverting 3-STATE outputs for bus-oriented applications
• Individual output enable control for each multiplexer section

Signal Switches, Multiplexers, Decoders Applications

• Bus-oriented system data selection
• Multiplexer expansion by tying outputs together
• Function generation involving multiple variables

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the component status as discontinued or obsolete before procurement planning. Confirm that the specific ordering suffix 'X' corresponds to tape and reel packaging requirements. Ensure compatibility with current supply chain alternatives if active sourcing is required for production continuity.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring dual independent 4-to-1 data routing within a compact surface-mount footprint. The AC series offers high-speed performance suitable for general digital logic applications. Verify voltage levels against system requirements, noting that ACT variants provide TTL-compatible inputs if necessary.
