74ACTQ16646
16-Bit Transceiver/Register with 3-STATE Outputs
General Description
The ACTQ16646 contains sixteen non-inverting bidirec-
tional registered bus transceivers providing multiplexed
transmission of data directly from the input bus or from the
internal storage registers. Each byte has separate control
inputs which can be shorted together for full 16-bit opera-
tion. The DIR inputs determine the direction of data flow
through the device. The CPAB and CPBA inputs load data
into the registers on the LOW-to-HIGH transition. The
ACTQ16646 utilizes Fairchild Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series features
GTO output control and undershoot corrector for superior
performance.
Features
a73 Utilizes Fairchild FACT Quiet Series technology
a73 Guaranteed simultaneous switching noise level and
dynamic threshold performance
a73 Guaranteed pin-to-pin output skew
a73 Independent registers for A and B buses
a73 Multiplexed real-time and stored data transfers
a73 Separate control logic for each byte
a73 16-bit version of the ACTQ646
a73 Outputs source/sink 24 mA
a73 Additional specs for Multiple Output Switching
a73 Output loading specs for both 50 pF and 250 pF loads
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
