Product Description
•
0.5 MICRON CMOS Technology
•
Guaranteed low skew < 350pS (max.)
•
Very low duty cycle distortion < 350pS (max.)
offers 1:10 fanout. The large fanout from a single input
•
High speed: propagation delay < 3nS (max.)
reduces loading on the preceding driver and provides an
•
Very low CMOS power levels
•
TTL compatible inputs and outputs
noise margins. Multiple power and grounds reduce noise.
•
1:10 fanout
Typical applications are clock and signal distribution.
•
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
The ASM2P3807A 3.3V clock driver is built using advanced
dual metal CMOS technology. This low skew clock driver
efficient clock distribution network. The ASM2P3807A
offers low capacitance inputs with hysteresis for improved

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, +25°C ambient.
3. Per TTL driven input (VIN = VCC -0.6V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the IC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input (VIN = VCC -0.6V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fi = Input Frequency
All currents are in milliamps and all frequencies are in megahertz.
