TC7W53FU,LF

Analog Switches - Special Purpose Overview

The TC7W53FU,LF is a high-speed C2MOS analog multiplexer/demultiplexer featuring a 2-channel configuration. It operates within a supply voltage range of VCC = 2 to 6 V and VEE = -6 to 0 V. The device achieves propagation delays as low as 15 ns (typical) at VCC = 5 V. Key electrical parameters include an ON-resistance of 50 Ω (typical) at VCC–VEE = 9 V and a quiescent supply current of 4 µA maximum at 25°C. It supports signal switching between VEE and VCC using small logical amplitude control signals.

Analog Switches - Special Purpose Feature Summary

• High-speed operation comparable to LSTTL with low power dissipation
• Low ON-resistance suitable for connecting to circuits with low input impedance
• High noise immunity with defined minimum noise margins
• High degree of linearity with low total harmonic distortion

Analog Switches - Special Purpose Applications

• Signal routing in systems requiring analog switch functionality
• Data acquisition systems utilizing low input impedance sensors
• Circuit designs needing pin and function compatibility with TC4W53

Analog Switches - Special Purpose Procurement Notes

Verify the specific package variant upon ordering, as the FU suffix denotes the SSOP8-P-0.65 package. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations are subject to change. Ensure that the design accounts for the absolute maximum ratings, particularly regarding supply voltage differentials and thermal dissipation limits.

Analog Switches - Special Purpose Selection Notes

Select this component when a 2-channel analog switch is required with high speed and low power consumption. It is appropriate for applications where the control logic operates at lower voltages than the switched signal path. Consider the TC4W53 if a direct pin-compatible alternative is needed. Evaluate the ON-resistance variation across temperature ranges to ensure signal integrity for the specific application load.

Analog Switches - Special Purpose Part Context

The TC7W53FU,LF belongs to the TC7W53 series of CMOS digital integrated circuits fabricated using silicon gate C2MOS technology. This series is designed to provide high-speed performance while maintaining the low power characteristics inherent to CMOS processes. The device serves as a multiplexer/demultiplexer, allowing digital control signals to route larger amplitude analog signals between channels.

Analog Switches - Special Purpose Replacement Considerations

The datasheet explicitly states that the TC7W53 is pin and function compatible with the TC4W53. Designers seeking a substitute should verify that the TC4W53 meets the specific electrical requirements, such as ON-resistance and propagation delay, for the intended application.
