Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT16500T and PI74FCT162500T are 18-bit registered bus
transceivers designed with D-type latches and flip-flops to allow
data flow in transparent, latched, and clocked modes. The Output
Enable (OEAB and OEBA), Latch Enable (LEAB and LEBA) and
Clock (CLKAB and CLKBA) inputs control the data flow in each
direction. When LEAB is HIGH, the device operates in transparent
mode for A-to-B data flow. When LEAB is LOW, the A data is latched
if CLKAB is held at a HIGH or LOW logic level. The A bus data is
stored in the latch/flip-flop on the HIGH-to-LOW transition of
CLKAB, if LEAB is LOW. OEAB performs the output enable
function on the B port. Data flow from B port to A port is similar using
OEBA, LEBA and CLKBA. These high-speed, low power devices
offer a flow-through organization for ease of board layout.
The PI74FCT16500T output buffers are designed with a Power-Off
disable allowing “live insertion” of boards when used as backplane
drivers.
The PI74FCT162500T has ±24 mA balanced output drivers. It is
designed with current limiting resistors at its outputs to control the
output edge rate resulting in lower ground bounce and undershoot.
This eliminates the need for external terminating resistors for most
interface applications.
