Replacement verdict
Not a drop-in replacement
The 74HC153D and 74HC132D,652 are functionally dissimilar logic ICs that cannot serve as substitutes for one another. The 74HC153D is a dual 4-to-1 multiplexer, while the 74HC132D,652 is a quad 2-input NAND Schmitt trigger. Their internal logic functions, input/output configurations, and intended circuit roles differ fundamentally, making direct replacement infeasible without complete circuit redesign.

Frequently asked questions
What are the primary functional differences between the 74HC153D and the 74HC132D,652?
The 74HC153D is a dual 4-input multiplexer that selects one of four data inputs per channel based on two select lines. The 74HC132D,652 contains four independent 2-input NAND gates with Schmitt-trigger inputs, providing hysteresis for slow or noisy input signals.
Are the 74HC153D and 74HC132D,652 pin-compatible?
No. The 74HC153D is typically supplied in a 16-pin SOIC package, while the 74HC132D,652 is supplied in a 14-pin SOIC package. Pin counts, pin functions, and PCB land patterns differ, so they are not drop-in replacements.
Can the 74HC153D and 74HC132D,652 operate from the same supply voltage range?
Yes. Both devices are 74HC-family CMOS logic parts and are specified for a nominal supply voltage range of 2.0 V to 6.0 V, with 5 V being the most common operating point.
Does the 74HC132D,652 provide Schmitt-trigger hysteresis on all inputs?
Yes. The 74HC132D,652 is a quad 2-input NAND Schmitt trigger. Each of its eight inputs has Schmitt-trigger hysteresis, which improves noise immunity and allows slow input transitions.
How many independent channels or gates does each device provide?
The 74HC153D provides two independent 4-input multiplexer channels, each with its own select inputs and output. The 74HC132D,652 provides four independent 2-input NAND gates.
Are the 74HC153D and 74HC132D,652 interchangeable in a logic design?
No. They perform different logic functions and have different pinouts and package sizes. Substitution requires redesign of the surrounding circuit and verification against the target design requirements.
What are the typical propagation delays for these devices?
At 5 V supply, the 74HC153D typically exhibits propagation delays in the range of approximately 10 ns to 20 ns depending on the input-to-output path. The 74HC132D,652 typically exhibits propagation delays in the range of approximately 10 ns to 25 ns, with hysteresis affecting both low-to-high and high-to-low transitions.
Do both devices support standard 74HC input and output voltage levels?
Yes. Both the 74HC153D and 74HC132D,652 comply with standard 74HC-family CMOS logic levels, allowing direct interfacing with other 74HC, 74HCT, and compatible CMOS logic devices within the specified supply voltage range.
