10 ns PLD for 5V glue-logic consolidation
The Microchip ATF16V8BQ-10JC is an electrically-erasable programmable logic device (EE PLD) from the 16V8 family, offering 8 macrocells with a 10 ns propagation delay. It operates from a single 5V supply and is supplied in a 20-lead PLCC (J-Lead) package measuring 9x9 mm.
Timing budget and logic capacity
The 10 ns propagation delay (tPD) sets the maximum system clock frequency for registered logic and the combinatorial delay path budget. At 5V, this speed grade supports system clocks up to about 50-60 MHz in typical registered applications, though the exact ceiling depends on the feedback path and output loading. The 8 macrocells can implement state machines, address decoders, or bus-interface logic that would otherwise occupy 4-8 small-scale logic packages.
The ATF16V8BQ-10JC carries an official lifecycle status of Obsolete.
The 20-lead PLCC (J-Lead) package has a 9x9 mm body with J-bend leads. This footprint is common across the 16V8 family and is socket-compatible with PLCC-20 sockets for prototyping or field-programmable applications.
