Very low CMOS power levels TTL compatible inputs and outputs 1:10 fanout Maximum output rise and fall time < 1.5nS (max.) Low input capacitance: 4.5pF typical Operates with 3.3V ± 0.3V Supply Inputs can be driven from 3.3V or 5V components Available in SSOP, SOIC, and QSOP Packages
ASM2P3807A
Product Description
The ASM2P3807A 3.3V clock driver is built using advanced dual metal CMOS technology. This low skew clock driver offers 1:10 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. The ASM2P3807A offers low capacitance inputs with hysteresis for improved noise margins. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution.
