CY54/74FCT374T
CY54/74FCT574T
Functional Description
Maximum Ratings[2, 3]
The FCT374T and FCT574T are high-speed low-power octal
D-type flip-flops featuring separate D-type inputs for each
flip-flop. Both devices have three-state outputs for bus orient-
ed applications. A buffered clock (CP) and output enable (OE)
are common to all flip-flops. The FCT574T is identical to
FCT374T except for flow-through pinout to simplify board de-
sign. The eight flip-flops contained in the FCT374T and
FCT574T will store the state of their individual D inputs that
meet the set-up and hold time requirements on the
LOW-to-HIGH clock (CP) transition. When OE is LOW, the
contents of the eight flip-flops are available at the outputs.
When OE is HIGH, the outputs will be in the high-impedance
state. The state of output enable does not affect the state of
the flip-flops.
(Above which the useful life may be impaired. For user guide-
lines, not tested.)
Storage Temperature .................................. -65°C to +150°C

Supply Voltage to Ground Potential ...............–0.5V to +7.0V
DC Input Voltage ............................................–0.5V to +7.0V
DC Output Voltage .........................................–0.5V to +7.0V
DC Output Current (Maximum Sink Current/Pin) ...... 120 mA
Power Dissipation.......................................................... 0.5W
Static Discharge Voltage ........................................... >2001V
(per MIL-STD-883, Method 3015)
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.

Notes:
1. H = HIGH Voltage Level. L = LOW Voltage Level X = Don’t Care Z = HIGH Impedance = LOW-to-HIGH clock transition
2. Unless otherwise noted, these limits are over the operating free-air temperature range.
3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.
4.
TA is the “instant on” case temperature.
5. Typical values are at VCC=5.0V, TA=+25°C ambient.
6. This parameter is guaranteed but not tested.
7. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameters tests. In any sequence of parameter
tests, IOS tests should be performed last.
