ADM483EARZ

Analog Devices · Buffers / Drivers · SOIC-8

ADM483EARZ from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output that is high if A > B by 200 mV and low if A < B by 200 mV when enabled.
2 RE input Receiver output enable, where a low level enables RO and a high level places RO in high impedance.
3 DE input Driver output enable, where a high level enables driver outputs A and B and a low level places them in high impedance.
4 DI input Driver input, where a logic low forces A low and B high and a logic high forces A high and B low when the driver is enabled.
5 GND power_in Ground connection, 0 V.
6 A bidirectional Noninverting receiver input A and driver output A, with ±15 kV HBM ESD protection and -7 V to +12 V common-mode range.
7 B bidirectional Inverting receiver input B and driver output B, with ±15 kV HBM ESD protection and -7 V to +12 V common-mode range.
8 VCC power_in Power supply, 5 V ± 10%.
