MC145406数据手册恩XP中文资料规格书

描述 Description

Overview The MC145406 has been discontinued. Suggested replacement: none.The MC145406 is a silicon-gate CMOS IC that combines three drivers and three receivers to meetthe electrical specifications of EIA Standard 232-E and CCITT V.28. The drivers feature true TTL input compatibility, slew-rate-limited output, 300 ohm power-off source impedance, and output typically switching to within 25% of the supply rails. The receivers canhandle up to +/- 25 V while presenting 3 to 7 k ohms impedance. Hysteresis in the receivers aidsin the reception of noisy signals. By combining both drivers and receivers in a single CMOS chip,the MC145406 provides efficient, low-power solutions for both EIA-232-E and V.28 applications.
