Philips Semiconductors Linear Products Product specification EIA-232-D/V.28 driver/receiver MC145406 DESCRIPTION The MC145406 is a silicon-gate CMOS IC that combines 3 drivers and 3 receivers to fulfill the electrical specifications of standards EIA-232-D and CCITT V.28. The drivers feature true TTL input compatibility, slew-rate limited output, 300Ω power-off source impedance, and output typically switching to within 25% of the supply rails. The receivers can handle up to +25V while presenting 3 to 7kΩ impedance. Hysteresis in the receiver aids reception of noisy signals. By combining both drivers and receivers in a single CMOS chip, the MC145406 provides efficient, low-power solutions for EIA-232-D and V.28 applications.
