概述
Description
MC100EPT21D is a high‑speed CMOS data selector/multiplexer from ON Semiconductor (MC100EPT family). It provides a 2:1 data select function: two data inputs (D0, D1) are routed to a single output under control of a select input (S). The device is used for fast data routing, timing and clock/data path applications in digital systems, offering low propagation delay and low skew with standard single‑supply CMOS levels. It’s typically employed in timing/bus switching, clock distribution, and other high‑speed routing tasks in telecoms and computers. The “D” suffix relates to packaging/grade variants; exact specs (Vcc, input/output levels, timing, and packaging) vary by device revision. For precise electrical characteristics and pinout, refer to the latest MC100EPT21D datasheet.
Equivalent
Equivalent parts depend on the device function and package; there isn’t a universal one-to-one substitute for MC100EPT21D. Please confirm:
- exact function (e.g., 2:1 data selector, demux, latch, etc.)
- package type (SOIC/DIP, etc.)
- speed/voltage requirements
- preferred vendor (TI, Onsemi, Nexperia, IDT, etc.)
With those, I can provide precise cross‑reference part numbers.
