FUNCTIONAL DESCRIPTION
IMISC462 eliminates the need for multiple oscillators and generates all the essential clock signals for the Personal
Computer Motherboards. supports 8086, 80286, 80386SX, 80386DX, 80486SX, 80486DX, 80486DX2, 80486 S Series,
and Pentium based designs. IMISC462 can be used with Green PC laptop or notebook computers to save power by
running the system slower than normal CPU speeds.

MAXIMUM RATINGS
Maximum Power Supply:
7 V
Vin Relative to VSS:
-0.3V to VDD+0.3
Storage Temperature:
-65C to + 150C
Opperating Temperature:
-55C to +125C
Maximum Power Disipation:
W
ESD:
12Kv(inputs), 2Kv (outputs)
Note. All Vdd and Vss pins must be connected to
their required potentials to aviod device damage
This device contains circuitry to protect the inputs
against damage due to high static voltages or electric
field; however, precautions should be taken to avoid
application of any voltage higher than the maximum
rated voltages to this circuit. For proper operation, Vin
and Vout should be constrained to the range:
VSS<(Vin or Vout)<VDD
Unused inputs must always be tied to an appropriate
logic voltage level (either VSS or VDD).
