54ACTQ657
Quiet Series Octal Bidirectional Transceiver with 8-Bit
Parity Generator/Checker and TRI-STATE® Outputs
General Description
The ACTQ657 contains eight non-inverting buffers with
TRI-STATE outputs and an 8-bit parity generator/checker. In-
tended for bus oriented applications, the device combines
the ’245 and the ’280 functions in one package.
The ACTQ utilizes NSC Quiet Series technology to guaran-
tee quiet output switching and improved dynamic threshold
performance. FACT Quiet Seriesfeatures GTOoutput
control and undershoot corrector in addition to a split ground
bus for superior performance.
Features
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Combines the ’245 and the ’280 functions in one
package
n Outputs source/sink 24 mA
n ’ACTQ has TTL-compatible inputs
n Standard Microcircuit Drawing (SMD)
