description

The SN74BCT899 is a 9-bit to 9-bit parity transceiver with transparent latches. The device can operate as a feed-through transceiver or it can generate/check parity from the 8-bit data buses in either direction. It has a current-sinking capability of 24 mA at the A bus and 64 mA at the B bus.

The SN74BCT899 features independent latch-enable (LEAB or LEBA) inputs, a select () input for ODD/ parity, and separate error-signal ( or ) outputs for checking parity.

The SN74BCT899 is characterized for operation from 0°C to 70°C.
