82C54 8254
$85.00
The Intel 82C54 is a high-performance, CHMOS version of the industry standard 8254 counter/timer which is designed to solve the timing control problems common in microcomputer system design. It provides three independent 16-bit counters, each capable of handling clock inputs up to 10 MHz. All modes are software programmable. The 82C54 is pin compatible with the HMOS 8254, and is a superset of the 8253.

CIRCUITO MULTIVIBRADOR DUAL MONOESTABLE. Each device is retriggerable and resettable. Triggering can occur from either the rising or falling edge of an input pulse,resulting in an output pulse over a wide range of widths. Pulse duration and accuracy are determined by external timing components Rx and Cx.
