and 200 V per Machine Model
Power up 3-State
Power-up reset
Live insertion/extraction permitted
DESCRIPTION
The 74ABT899 is a 9-bit to 9-bit parity transceiver with separate
transparent latches for the A bus and B bus. Either bus can
generate or check parity. The parity bit can be fed-through with no
change or the generated parity can be substituted with the SEL
input.
Parity error checking of the A and B bus latches is continuously
provided with ERRA and ERRB, even with both buses in 3-State.
The 74ABT899 features independent latch enables for the A and B
bus latches, a select pin for ODD/EVEN parity, and separate error
signal output pins for checking parity.
FUNCTIONAL DESCRIPTION
The 74ABT899 has three principal modes of operation which are
outlined below. All modes apply to both the A-to-B and B-to-A
directions.
Transparent latch, Generate parity, Check A and B bus parity:
Bus A (B) communicates to Bus B (A), parity is generated and
passed on to the B (A) Bus as BPAR (APAR). If LEA and LEB are
High and the Mode Select (SEL) is Low, the parity generated from
A0-A7 and B0-B7 can be checked and monitored by ERRA and
ERRB. (Fault detection on both input and output buses.)
Transparent latch, Feed-through parity, Check A and B bus
parity:
Bus A (B) communicates to Bus B (A) in a feed-through mode if SEL
is High. Parity is still generated and checked as ERRA and ERRB
and can be used as an interrupt to signal a data/parity bit error to the
CPU.
Latched input, Generate/Feed-through parity, Check A (and B)
bus parity:
Independent latch enables (LEA and LEB) allow other permutations of:
Transparent latch / 1 bus latched / both buses latched
Feed-through parity / generate parity
Check in bus parity / check out bus parity / check in and out bus
