75185

UNISONIC TECHNOLOGIES CO., LTD 75185 MULTIPLE RS-232 DRIVERS AND RECEIVERS DESCRIPTION The UTC 75185 complies with the requirements of the TIA/EIA232-F and ITU (formerly CCITT) v.28 standards. These standards are for data interchange between a host computer and peripheral at signaling rates up to 20kbit/s. The switching speeds of the UTC 75185 are fast enough to support rates up to 120kbite/s with lower capacitive loads (shorter cables). Interoperability at the higher signaling rates cannot be assured unless the designer has design control of the cable and the interface circuits at both ends. For interoperability at signaling rates to 120kbit/s, use of ITA/EIA-423-B (ITU v.10) and TIA/EIA-422-B (ITU v.11) standards are recommended. LINEAR INTEGRATED CIRCUIT TSSOP-20 SSOP-20 SOP-20 DIP-20 FEATURES *Single Chip with Easy Interface between UART and Serial-Port connector of PC. *Three Drivers and five Receivers Meet or Exceed the Requirements of TIA/EIA-232-F and ITU v.28 Standards. *Designed to Support Data Rates up to 120 kbps ORDERING INFORMATION Normal 75185-D20-T 75185-P20-R 75185-R20-R 75185-S20-R Ordering Number Lead Free Plating 75185L-D20-T 75185L-P20-R 75185L-R20-R 75185L-S20-R Halogen Free 75185G-D20-T 75185G-P20-R 75185G-R20-R 75185G-S20-R Package DIP-20 TSSOP-20 SSOP-20 SOP-20 Packing Tube Tape Reel Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd 1 of 10 QW-R113-003,F 75185 PIN CONFIGURATIONS VDD RA1 RA2 RA3 DY1 DY2 RA4 DY3 RA5 VSS 1 2 3 4 5 6 7 8 9 10 LINEAR INTEGRATED CIRCUIT 20 19 18 17 16 15 14 13 12 11 VCC RY1 RY2 RY3 DA1 DA2 RY4 DA3 RY5 GND PIN DESCRIPTION PIN NO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 SYMBOL VDD RA1 RA2 RA3 DY1 DY2 RA4 DY3 RA5 VSS GND RY5 DA3 RY4 DA2 DA1 RY3 RY2 RY1 VCC PIN DESCRIPTION Supply Voltage First Receiver Input Second Receiver Input Third Receiver Input First Driver Output Second Driver Output Fourth Receiver Input Third Driver Output Fifth Receiver Input Supply Voltage Ground Fifth Receiver Output Third Driver Input Fourth Receiver Output Second Driver Input First Driver Input Third Receiver Output Second Receiver Output First Receiver Output Supply Voltage UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 10 QW-R113-003,F 75185 PARAMETER Supply Voltage (Note 1) Input Voltage Range Driver Output Voltage Range Receiver Low Level Output Current Storage Temperature Range Drive Receiver SYMBOL VDD VSS VCC VIN VOUT IOUT TSTG LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS OVER OPERATING FREE-AIR TEMPERATURE RANGE (unless otherwise specified) RATINGS 15 -15 10 -15 ~ 7 -30 ~ 30 -15~ 15 20 -65 ~ +150 UNIT V V V V V V mA °C THERMAL DATA PARAMETER DIP-20 Junction to Ambient SYMBOL RATINGS 70 UNIT SOP-20 100 θJA °C/W SSOP-20 115 TSSOP-20 115 Note 1: All voltage are with respect to the network ground terminal.
