SY89850U February 2005 2 M9999-020305 hbwhelp@micrel.com or (408) 955-1690 Ordering Information (1) Part Number Package Type Operating Range Package Marking Lead Finish SY89850UMG MLF-8 Industrial 850U with Pb-Free bar-line indicator NiPdAu Pb-Free SY89850UMGTR (2) MLF-8 Industrial 850U with Pb-Free bar-line indicator NiPdAu Pb-Free Notes: 1. Contact factory for dice availability. Dice are guaranteed at TA = 25°C, DC Electrical Only. 2. Tape and Reel. Pin Configuration 8-Pin MLF™ (MLF-8) Pin Description Pin Number Pin Name Pin Function 1, 4 IN, /IN Differential Input: This input pair is the signal to be buffered. These inputs accept AC- or DC-coupled signals as small as 100mV. Each pin of this pair internally terminates to a VT pin through 50Ω. Note that this input will default to an indeterminate state if left open. Please refer to the “Input Interface Applications” section for more details. 2 VT Input Termination Center-Tap: Each side of the differential input pair terminates to this pin. The VT pin provides a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section for more details. 3 VREF-AC Reference Output Voltage: This output biases to VCC –1.2V. Connect to VT pin when AC-coupling the input. Bypass with 0.01 µF low ESR capacitor to VCC. Maximum sink/source current is ±1.5mA. Due to the limited drive capability, the VREF-AC pin is only intended to drive its respective VT pin. See “Input Interface Applications” section. 5 GND, Exposed Pad Ground: Ground pin and exposed pad must be connected to the same ground plane. 7, 6 Q, /Q Differential 100K LVPECL Output: This LVPECL output is the output of the device. Terminate through 50Ω to VCC–2V. See “Output Interface Applications” section. 8 VCC Positive Power Supply: Bypass with 0.1 µF//0.01µF low ESR capacitors as close to the VCC pin as possible. |
