Description
www.DataSheet4U.com ML145403 ML145404 ML145405 ML145408 Drivers/Receivers RS 232/EIA–232–E and CCITT V.28 Legacy Device: Motorola MC145403, MC145404, MC145405, MC145408 These 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: Operating Temperature Range TA = –40° to +85°C 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 Available Driver/Receiver Combinations Device ML145403 ML145404 ML145405 ML145408 Drivers 3 4 5 5 Receivers 5 4 3 5 Figure 1 2 3 4 No. of Pins 20 20 20 24 Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part...
