IDT74FCT807BT/CT FAST CMOS 1-TO-10 CLOCK DRIVER COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS IDT74FCT807BT/CT 1-TO-10 CLOCK DRIVER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT807T clock driver is built using advanced dual metal CMOS Guaranteed low skew < 250ps (max.) technology. This low skew clock driver features 1:10 fanout, providing Very low duty cycle distortion < 350ps (max.) minimal loading on the preceding drivers. The FCT807T offers low High speed: propagation delay < 2.5ns (max.) capacitance inputs with hysteresis for improved noise margins. TTL level 100MHz operation outputs and multiple power and grounds reduce noise. The device also TTL compatible inputs and outputs features -32/48mA drive capability for driving low impedance traces. TTL level output voltage swings 1:10 fanout Output rise and fall time < 1.5ns (max) Low input capacitance: 4.5pF typical High drive: -32mA IOH, +48mA IOL Available in QSOP, SSOP, and SOIC packages FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION O1 1 20 VCC IN O2 19 2 GND O10 3 18 O1 O9 O3 4 17 VCC GND 5 16 O2 O8 O4 6 15 GND VCC 7 14 O3 O7 O5 8 13 CC GND V IN 9 12 O4 O6 O6 10 11 GND O5 O7 QSOP/ SOIC/ SSOP TOP VIEW O8 O9 O10 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
