Am8253/Am8253-5 Programmable Interval Timer ADVANCED INFORMATION DISTINCTIVE CHARACTERISTICS • Count binary or BCD • Single +5V supply • 24-pin dual-in-line package • Three independent 16-bit counters • DC to 2.5MHz • Programmable counter modes • Bus oriented I/O • 100% reliability assurance testing to MIL-STD-883 GENERAL DESCRIPTION The Am8253/Am8253-5 are programmable counter/timer chips designed for use as Am8080NAm8085A Family peripherals. They use NMOS technology with a single +5V supply and are direct replacements for Intel's 8253/8253-5. Each device is organized as three independent 16-bit counters, each counter having a rate of up to 2.5MHz. All modes of operation are software programmable. For improved performance, see Am9513 System Timing Controller.
