description
The AM26S10C is a quadruple bus transceiver utilizing Schottky-diode-clamped transistors for high speed. The
drivers feature open-collector outputs capable of sinking 100 mA at 0.8 V maximum. The driver and strobe
inputs use pnp transistors to reduce the input loading.
The driver of the AM26S10C is inverting and has two ground connections for improved ground current-handling
capability. For proper operation, the ground pins should be tied together.
The AM26S10C is characterized for operation over the temperature range of 0°C to 70°C.
