Product details

Supply voltage and logic-level compatibility

The 2V to 5.5V supply range lets this OR gate bridge 3.3V and 5V domains without a level shifter in many cases. Input thresholds are specified at 0.5V low and 1.5V high, which means a 3.3V CMOS output drives it cleanly, and a 5V TTL output also meets the high threshold. This simplifies BOM consolidation when mixing voltage rails on a single board.

Propagation delay and output drive

At 7.5ns max propagation delay (5V, 50pF), this gate handles clock distribution and control signal gating up to moderate speeds without adding timing margin headaches. The 12mA symmetric output drive is enough to fan out to multiple CMOS loads or drive a short trace directly. For longer backplane runs or higher capacitive loads, consider a bus buffer or line driver.

Lifecycle and compliance

The 14-SOIC package is widely second-sourced, and the 74LV logic family has broad cross-vendor availability, reducing single-source risk.

Frequently asked questions

Is SN74LV32ADR compatible with 5V logic?

Yes. With a 5V supply, the input high threshold of 1.5V is well below a 5V CMOS or TTL high output, and the outputs swing rail-to-rail. The 12mA drive at 5V is sufficient for standard 5V logic loads.

Is SN74LV32ADR RoHS compliant?

Yes, it is ROHS3 compliant per the lifecycle record.

What is the propagation delay of SN74LV32ADR?

Maximum propagation delay is 7.5ns at 5V with a 50pF load. This is the figure to use for timing closure in your design.
