DESCRIPTION

FEATURES

■ Differential D, CLK and Q

■ Extended 100E VEE range of –4.2V to –5.5V

■ VBB output for single-ended use

■ 1100MHz min. toggle frequency

■ Asynchronous Master Reset

■ Fully compatible with Motorola MC10E/100E452

■ Available in 28-pin PLCC package

The SY10/100E452 are 5-bit differential registers with

differential data (inputs and outputs) and clock. The

registers are triggered by a positive transition of the

positive clock (CLK) input. A high on the Master Reset

(MR) asynchronously resets all registers so that the Q

outputs go LOW.

The differential input structures are clamped so that

the inputs of unused registers can be left open without

upsetting the bias network of the devices. The clamping

action will assert the /D and the /CLK sides of the inputs.

Because of the edge-triggered flip-flop nature of the

devices, simultaneously opening both the clock and data

inputs will result in an output which reaches an

unidentified but valid state.

The fully differential design of the devices makes them

ideal for very high frequency applications where a

registered data path is necessary.

NOTE:

1. VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the input signals are within the VCMR range

and the input swing is greater than VPP (min.) and <1V.
