RAA788150, RAA788152, RAA788153, RAA788155, RAA788156, RAA788158 Datasheet 2.2 Pin Descriptions 8 Ld 10 Ld 14 Ld Pin SOIC MSOP SOIC Name Function
1 1 2 RO Receiver output: If A-B ≥ -50mV, RO is high; If A-B ≤ -200mV, RO is low. RO is fail-safe High if A and B are unconnected (open) or shorted. 2 2 3 RE Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. 3 3 4 DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low. 4 4 5 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 5 6, 7 GND Ground connection. 6 – – A/Y Non-inverting receiver input and non-inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. 7 – – B/Z Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. – 6 9 Y Non-inverting driver output. – 7 10 Z Inverting driver output. – 8 11 B Inverting receiver input. – 9 12 A Non-inverting receiver input. 8 10 – VCC System power supply input (4.5V to 5.5V). – – 1, 8, 13 NC No connection.
