PI74HSTL1212
Product Description
PericomSemiconductor’sPI74HSTL1212consistsoftwo12-Bitbi-
directional non-inverting tranceivers with two separate supply
rails,A-Port(VCCA)setat1.8V,andB-Port(VCCB)setat3.3V.Each
set of 12 tranceivers allows translation from a 1.8V to 3.3V and back
again. The control inputs 1DAB/1DBA and 2DAB/2DBA allows
independent 12-Bit slice direction control for greater flexibility.
The PI74HSTL1212 is particularly useful for asynchronous
communications between HSTL and LVTTL/LVCMOS data buses.
