The INS8253 is a programmable timer/counter device contained in a standard, 24-pin dual-in-line package. The chip, which is fabricated using N-channel silicon gate technology, provides counting or time-out services in a microcomputer system. The various operating modes and other functional characteristics of thelNS8253 are programmed by the system software. .
• 3 Individually Programmable 16-Bit Counters
• 6 Operating Modes
• DC to 2MHz Count Rates
• Individual Count Rate and Modulus for Each Counter
• Selectable Counting System (Binary or BCD) for Each Counter
• TRI-STATE@ TTL Drive Capability for Bidirectional Data Bus
• Single + 5 Volt Power Supply
• 24-Pin Dual-in-Line Package
• MICROBUSTM' Compatible
