CD74HCT4052EE4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4052EE4 is a high-speed CMOS analog multiplexer and demultiplexer manufactured by Texas Instruments. It features two independent 4-to-1 channels with bidirectional switching capabilities. The device operates within a supply voltage range of 4.5V to 5.5V for the HCT logic family, supporting an analog signal voltage range from VEE to VCC. Key electrical parameters include a typical ON-resistance of 70Ω at VCC – VEE = 4.5V and low crosstalk between switches. It provides direct LSTTL input logic compatibility with a maximum VIL of 0.8V and minimum VIH of 2V. The component supports break-before-make switching and functions reliably across an operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Direct LSTTL input logic compatibility ensures seamless integration with TTL-based control systems without additional level shifting.
• Bidirectional switch architecture allows any analog input channel to function as an output and vice versa, providing flexible signal routing.
• Break-before-make switching action prevents momentary short circuits between channels during state transitions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EE4 corresponds to the intended PDIP-16 package configuration and lead-free manufacturing status. Confirm that the HCT logic family requirements align with the system's 4.5V to 5.5V supply constraints. Ensure ESD handling protocols are followed due to the sensitivity of CMOS inputs. Cross-reference the datasheet revision date to confirm current specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when TTL-compatible digital control is required for analog signal routing. The HCT series is appropriate for systems powered by standard 5V logic supplies. Consider the dual 4:1 channel structure for applications requiring simultaneous selection of two separate signal paths. Verify that the analog signal amplitude remains within the VEE to VCC limits to ensure proper switch operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CDx4HC405x and CDx4HCT405x family of high-speed CMOS analog multiplexers. It shares functional similarities with the HC variant but differs in input threshold levels to support TTL compatibility. The device utilizes silicon gate CMOS technology to achieve operating speeds comparable to LSTTL while maintaining low power consumption typical of standard CMOS integrated circuits.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

CD74HC4052EE4 serves as a compatible alternative where HC logic thresholds are acceptable instead of HCT. CD74HCT4052PWRE4 offers identical functionality in a TSSOP surface-mount package. CD74HC4352E provides similar dual 4:1 multiplexing capabilities but requires verification of pinout and package differences.
