.. 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 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 MC145408P MC145403DW MC145404DW MC145405DW MC145408DW MC145405SD Plastic DIP Plastic DIP Plastic DIP Plastic DIP SOG Package SOG Package SOG Package SOG Package SSOP REV 2 1/97 TN97010600 ©...
