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
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series
