DESCRIPTION:

dual metal CMOS technology. These high-speed, low-power 18-bit registered

bus transceivers combine D-type latches and D-type flip-flops to allow data flow

in transparent, latched and clocked modes. Data flow in each direction is

controlled by output-enable (OEAB and OEBA), latch enable (LEAB and LEBA)

and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the device

operates in transparent mode when LEAB is high. When LEAB is low, the A data

is latched if CLKAB is held at a high or low logic level. If LEAB is low, the A bus

data is stored in the latch/flip-flop on the low-to-high transition of CLKAB. OEAB

is the output enable for the B port. Data flow from the B port to the A port is similar

but requires using OEBA, LEBA and CLKBA. Flow-through organization of

signal pins simplifies layout. All inputs are designed with hysteresis for improved

noise margin.

This offers low ground bounce, minimal undershoot, and controlled output fall

times–reducing the need for external series terminating resistors. The

FCT162501T is a plug-in replacement for the FCT16501T and ABT16501 for

on-board bus interface applications.

The FCT162501T 18-bit registered transceivers are built using advanced

The FCT162501T has balanced output drive with current limiting resistors.
