Product details

The ATF16V8C-7SC is a 5V EE PLD from Microchip's 16V8 family, offering a 7.5 ns propagation delay and 8 macrocells in a 20-SOIC surface-mount package.

Obsolete — sourcing through the surplus channel

Microchip lists the ATF16V8C-7SC as Obsolete. For production BOMs that still call out this exact speed grade and package, the supply path runs through independent distribution — sealed reels with consistent date-codes from factory excess or end-of-life buyouts.

8 macrocells — fitting the glue-logic budget

Eight macrocells can each be configured as registered or combinatorial outputs. The 5V-only supply simplifies integration into legacy 5V backplanes and industrial control cards.

20-SOIC footprint — board-space and layout constraints

The 20-SOIC package with 0.295-inch (7.50 mm) body width is the wider variant — distinct from the narrow SOIC-20. Confirm the footprint matches the existing PCB land pattern.

Frequently asked questions

What is the replacement for ATF16V8C-7SC?

No official replacement order code is listed by Microchip. The closest functional alternative within the 16V8 family is the ATF16V8C-7PU (PDIP-20) or ATF16V8C-7SX (narrow SOIC-20), but neither is a drop-in replacement — the package differs. For a pin-compatible surface-mount substitute, the ATF16V8C-7SC's 20-SOIC (7.50 mm body) footprint must be matched; the ATF16V8C-7SX uses the narrow 0.209-inch body. Verify the land pattern before substituting.

What is ATF16V8C-7SC's speed grade?

The ATF16V8C-7SC is rated for a 7.5 ns propagation delay (tpd). This is the commercial speed grade — the fastest in the ATF16V8C family — and supports system clocks up to roughly 100 MHz for registered logic functions.
