Thus, this is a. Enable input will latch the number in the counters into the. Segment resistors are desirable to minimize power dissipa. Low, displays output of latch. Pin Assignments for DIP. This input signal should not be allowed.
When using this driver with a 5V supply at room temperature, the display can be driven without segment resistors datashewt full illu- mination. This input signal should not be allowed. The multiplexing circuit has its own free-running oscillator, and requires no external clock. The multiplexing circuit has its own.

Thus input signals exceeding V CC will not be clamped. Features datssheet Wide supply voltage range: The input protection circuitry consists of a series resistor. View PDF for Mobile. AC Parameters are guaranteed by DC correlated testing. Display Select — High, displays output of counter. AC Electrical Characteristics Note 3. Fairchild Semiconductor Electronic Components Datasheet. Enable input will latch the number in the counters into the.
The input protection circuitry consists of a series resistor, and a diode to ground.
The user must use caution in this mode however. Enable, Clock and Reset inputs. The MM74C is a 4-decade counter and has Latch.
Thus, this is a. Thus, if the clock input frequency is 10 Hz, the display would read tenths of seconds and minutes i. A LOW signal on the Latch Enable input will latch the number in the counters into the internal output latches. Latch Catasheet — High, flow through condition. The input protection circuitry consists of a series resistor.
