SN54ABT833, SN74ABT833
8-BIT TO 9-BIT PARITY BUS TRANSCEIVERS
SCBS195C – FEBRUARY 1991 – REVISED JANUARY 1997

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT833 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74ABT833 is characterized for operation from –40
°
C to 85
°
C.

Summation of high-level inputs includes PARITY along with Bi inputs.
Output states shown assume ERR was previously high.
§In this mode, ERR (when clocked) shows inverted parity of the A bus.
