Functional Description

These 16-bit registered transceivers are high-speed,

low-power devices. 16-bit operation is achieved by connecting

the control lines of the two 8-bit registered transceivers

together. For data flow from bus A-to-B, CEAB must be LOW

to allow data to be stored when CLKAB transitions from

LOW-to-HIGH. The stored data will be present on the output

when OEAB is LOW. Control of data from B-to-A is similar and

is controlled by using the CEBA, CLKBA, and OEBA inputs.

The output buffers are designed with a power-off disable

feature to allow for live insertion of boards.

The CY74FCT16952T is ideally suited for driving

high-capacitance loads and low-impedance backplanes.

The CY74FCT162952T has 24-mA balanced output drivers

with current-limiting resistors in the outputs. This reduces the

need for external terminating resistors and provides for

minimal undershoot and reduced ground bounce. The

CY74FCT162952T is ideal for driving transmission lines.

The CY74FCT162H952T is a 24-mA balanced output part that

has “bus hold” on the data inputs. The device retains the

input’s last state whenever the input goes to high impedance.

This eliminates the need for pull-up/down resistors and

prevents floating inputs.
