ADM488 8-Lead PDIP/SOIC Pin Configuration Table 4. ADM488 Pin Function Descriptions Pin No. Mnemonic Description 1 VCC Power Supply, 5 V ± 10%. 2 RO Receiver Output. When A > B by 200 mV, RO = high. If A < B by 200 mV, RO = low. 3 DI Driver Input. A logic low on DI forces Y low and Z high, while a logic high on DI forces Y high and Z low. 4 GND Ground Connection, 0 V. 5 Y Noninverting Driver, Output Y. 6 Z Inverting Driver, Output Z. 7 B Inverting Receiver, Input B. 8 A Noninverting Receiver, Input A.

ADM489 16-Lead TSSOP Pin Configuration Table 5. ADM489 Pin Function Descriptions PDIP/SOIC Pin No. TSSOP Pin No. Mnemonic Description 1, 8, 13 2, 9, 10, 13, 16 NC No Connect. No connections are required to this pin. 2 3 RO Receiver Output. When enabled, if A > B by 200 mV then RO = high. If A < B by 200 mV then RO = low. 3 4 RE Receiver Output Enable. A low level enables the receiver output, RO. A high level places it in a high impedance state. 4 5 DE Driver Output Enable. A high level enables the driver differential outputs, Y and Z. A low level places it in a high impedance state. 5 6 DI Driver Input. When the driver is enabled, a logic low on DI forces Y low and Z high, while a logic high on DI forces Y high and Z low. 6, 7 7, 8 GND Ground Connection, 0 V. 9 11 Y Noninverting Driver, Output Y. 10 12 Z Inverting Driver, Output Z. 11 14 B Inverting Receiver, Input B. 12 15 A Noninverting Receiver, Input A. 14 1 VCC Power Supply, 5 V ± 10%. |
