Product Description
Pericom Semiconductor’s PI74HSTL1212 consists of two 12-Bit bi-
directional non-inverting tranceivers with two separate supply
rails, A-Port (V
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.
