Product details

The STMicroelectronics UA741IDT is a single-circuit, general-purpose operational amplifier in an 8-SOIC package. It delivers a 1 MHz gain-bandwidth product and a 0.5 V/µs slew rate, with a supply span from 10 V to 44 V. The industrial temperature range of -40°C to 105°C makes it a candidate for motor-drive feedback, power-supply control loops, and sensor conditioning in factory or outdoor telecom environments.

Lifecycle and compliance

The UA741IDT is listed as Active and ROHS3 compliant. No last-time-buy or obsolescence notice is on record.

Package and mounting

Surface-mount 8-SOIC (0.154" width, 3.90 mm body). The supplier device package is 8-SOIC. Available in Tape & Reel or Cut Tape — the reel option suits automated pick-and-place; Cut Tape works for prototype or low-volume builds.

Frequently asked questions

What is the UA741IDT slew rate?

The UA741IDT slew rate is 0.5 V/µs. This limits large-signal response; for faster settling, consider a device with a higher slew rate like the LM258A at 0.6 V/µs.

What is the equivalent or replacement for UA741IDT?

The MC3303DT is a quad general-purpose op-amp with similar 1 MHz GBW and 0.5 V/µs slew rate, but it is a quad device in a different package (SO-14). For a single-channel replacement, the LM258A is a dual op-amp with 1.1 MHz GBW and 0.6 V/µs slew rate — board layout changes required. Neither is a pin-compatible drop-in; verify your circuit's channel count and package before substituting.

Is UA741IDT available via RFQ confirmation? What is the lead time?

Stock and lead time vary by distributor. The part is actively manufactured and available through independent channels. For current stock levels and lead time, request a quote — we confirm availability at quote time.
