.. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145403/D MC145403 Drivers/Receivers MC145404 MC145405 MC145408 EIA- 232- E and CCITT V.28 These devices are silicon gate CMOS ICs that bine 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 patibility, 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 bining 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 patible 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 patible 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 binations 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 CASE 751E 1 20 1 SD SUFFIX SSOP CASE 940B Alternative EIA- 232 devices to consider are: Three Supply MC145406 (3 x 3) Single Supply MC145407 (3 x 3) MC145705 (2 x 3) with Power Down MC145706 (3 x 2) with Power Down MC145707 (3 x 3) with Power Down ORDERING INFORMATION MC145403P MC145404P MC145405P...
