Drivers/Receivers EIA-232-E and CCITT V.28
EIA–232–E and CCITT V.28These devices are silicon gate CMOS ICs that combine both the transmitter
and receiver to fulfill the electrical specifications of EIA Standard 232–E and
CCITT V.28. The drivers feature true TTL input compatibility, slew rate limiting
outputs, 300 Ω power–off source impedance, and output typically switching to
within 25% of the supply rails. The receivers can handle up to ± 25 V while
presenting 3 to 7 kΩ impedance. Hysteresis in the receivers aid in the reception
of noisy signals. By combining both drivers and receivers in a single CMOS
chip, these devices provide efficient, low–power solutions for both EIA–232–E
and V.28 applications.
These devices offer the following performance features:
Drivers•± 5 to ± 12 V Supply Range 300 Ω Power–Off Source Impedance Output Current Limiting TTL and CMOS Compatible Inputs Driver Slew Rate Range Limited to 30 V/μs Maximum
Receivers•± 25 V Input Range 3 to 7 kΩ Input Impedance 0.8 V of Hysteresis for Enhanced Noise Immunity TTL and CMOS Compatible Outputs
