DESCRIPTION:

•
•
•
The IDT54/74FCT161T/163T, IDT54/74FCT161AT/ 163AT
and IDT54/74FCT161CT/163CT are high-speed synchronous modulo-16 binary counters 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
IDT54/74FCT161T/AT/CT have asynchronous Master Reset
inputs that override all other inputs and force the outputs LOW.
The IDT54/74FCT163T/AT/CT have Synchronous Reset inputs that override counting and parallel loading and allow the
outputs to be simultaneously reset on the rising edge of the
clock.

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.
2. Input and VCC terminals only.
3. Outputs and I/O terminals only.

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.
