SY100E457 DESCRIPTION FEATURES ■ Differential D and Q ■ Extended 100E VEE range of –4.2V to –5.5V ■ ■ ■ ■ ■ ■ SY10E457 SY100E457 SY10E457 TRIPLE DIFFERENTIAL 2:1 MULTIPLEXER Micrel, Inc. The SY10/100E457 are 3-bit differential 2:1 multiplexers. The fully differential data path makes the devices ideal for multiplexing low skew clock or other skew sensitive signals. Multiple VBB pins are provided to ease AC coupling input signals. The higher frequency outputs provide the device with a >1.0GHz bandwidth to meet the needs of the most demanding system clock. Both separate selects and a common select are provided to make the device well suited for both data path and random logic applications. VBB output for single-ended use 700ps max. propagation delay High frequency outputs Separate and common select Internal 75KΩ input pulldown resistors Available in 28-pin PLCC package PIN NAMES BLOCK DIAGRAM Pin D0a D0a D0b D0b H 2:1 MUX L Q0 Q0 SEL0 D1a D1a H D1b D1b L 2:1 MUX Function Dn[0:2], Dn[0:2] Differential Data Inputs SEL Individual Select Input COMSEL Common Select Input VBB VBB Reference Output Q[0:2], Q[0:2] Differential Data Outputs VCCO VCC to Output Q1 Q1 SEL1 D2a D2a H D2b D2b L 2:1 MUX Q2 Q2 SEL2 COMSEL VBB M9999-032206 [email protected] or (408) 955-1690 Rev.: F 1 Amendment: /0 Issue Date: March 2006 SY10E457 SY100E457 Micrel, Inc.

Differential input voltage required to obtain a full ECL swing on the outputs. 2. 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.
