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 ± 25 V Input Range 3 to 7 kΩ Input Impedance 0.8 V of Hysteresis for Enhanced Noise Immunity TTL and CMOS Compatible Outputs 24 24 1 20 1 P SUFFIX PLASTIC DIP CASE 738 P SUFFIX PLASTIC DIP CASE 724 Receivers 20 1 DW SUFFIX SOG PACKAGE CASE 751D Available Driver/Receiver Combinations Device MC145403 MC145404 MC145405 MC145408 Drivers 3 4 5 5 Receivers 5 4 3 5 Figure 1 2 3 4 No. of Pins 20 20 20 24 DW SUFFIX SOG PACKAGE CAS...
