−
The FCT163T is a high-speed synchronous modulo-16 binary counter
built using an advanced dual metal CMOS technology. They are synchronously presettable for application in programmable dividers and have two
types of count enable inputs plus a terminal count output for versatility in
forming synchronous multi-stage counters. The FCT163T has Synchronous Reset inputs that override counting and parallel loading and allow the
outputs to be simultaneously reset on the rising edge of the clock.
Std., A and C speed grades
Low input and output ≤1µ A (max.)
CMOS power levels
True TTL input and output compatibility
• – VOH = 3.3V (typ.)
• – VOL = 0.3V (typ.)
High drive outputs (-15mA IOH, 48mA IOL)
Meets or exceeds JEDEC standard 18 specifications
Military product compliant to MIL-STD-883, Class B and DESC
listed (dual marked)
Power off disable outputs permit “live insertion”
Available in the following packages:
• Industrial: SOIC, QSOP
• Military: CERDIP, LCC, CERPACK

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
No
terminal voltage may exceed Vcc by +0.5V unless otherwise noted.

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 = 5.0V, +25°C ambient.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. The test limit for this parameter is ±5µ A at TA = -55°C.
5. Clock pin requires a minimum VIH of 2.5V.

2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V). 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 ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCP/2 + fiNi)
ICC = Quiescent Current
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
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)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
