Part Details:

74F899 9-Bi February 1989 Revised August 1999 t Latcha 74F8999-Bit Latchable Transceiverwith Parity Generator/Checker ble T General Description Features r The 74F899 is a 9-bit to 9-bit parity transceiver with trans- s Latchable transceiver with output sink of 24 mA at the ans parent latches. The device can operate as a feed-through A-bus and 64 mA at the B-bus transceiver or it can generate/check parity from the 8-bit s Option to select generate parity and check or ceiver data busses in either direction. It has a guaranteed current "feed-through" data/parity in directions A-to-B or B-to-A sinking capability of 24 mA at the A-bus and 64 mA at the s Independent latch enables for A-to-B and B-to-A B-bus. directions The 74F899 features independent latch enables for the s Select pin for ODD/EVEN parity A-to-B direction and the B-to-A direction, a select pin for ODD/EVEN parity, and separate error signal output pins for s ERRA and ERRB output pins for parity checking checking parity. s Ability to simultaneously generate and check paritys May be used in systems applications in place of the 74F543 and 74F280 s May be used in system applications in place of the 74F657 and 74F373 (no need to change T/R to checkparity) Ordering Code: Order Number Package Number Package Description 74F899SC M28B 28-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 74F899QC V28A 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square Devices also available in Tape and Reel.
