2 / 8 page UTRS485 CMOS IC UNISONICTECHNOLOGIESCO.,LTD 2 of 8 www.unisonic.com.tw QW-R113-011.G MARKING PIN CONFIGURATION 1 2 3 4 8 7 6 5 RO RE DE DI VCC B A GND PIN DESCRIPTION PIN NO. PIN NAME DESCRIPTION 1 RO Receiver output: if A>B by 200mV, RO will be high; if A<B by 200mV, RO will be low. 2 RE Receiver output enable. RO is enable when RE is low; RO is high impedance when RE is high. 3 DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low. If the driver outputs are enabled, the parts function as line drivers. While they are high impedance, they function as line receivers if RE is low. 4 DI Driver Input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low. 5 GND Ground 6 A Non-inverting receiver input and non-inverting driver output 7 B Inverting receiver input and inverting driver output 8 VCC Positive supply; 4.75V≤VCC≤5.25V |
