Product Code : SCL-EELE-12720
Indian Lab Suppliers supplies the 8253 Programmable Timer (Product ID: 12720) as part of its electronics engineering lab equipment range. It studies all six operating modes of the 8253 programmable interval timer.
Quick Answer
The modes are: 0, interrupt on terminal count; 1, programmable one-shot; 2, rate generator; 3, square-wave generator; 4, software-triggered strobe; and 5, hardware-triggered strobe. A 555 timer provides the clock, SPDT switches set the control and gate levels, and LEDs and waveform terminals show the counter outputs for each mode. The 8253 contains three independent 16-bit counters. A 5 V, 500 mA regulated supply is built in, and the board runs from 230 V ±10%, 50 Hz mains with fuse and jewel light. Operating instructions with theory, design procedure and report suggestions are supplied.
