The multiplexing circuit has its own free-running oscillator, and requires no external clock. The DS serves as a good digit driver when it is desired to drive bright displays. Thus input signals exceeding V CC will not be clamped.

Latch Enable — High, flow through condition. The input protection circuitry consists of a series resistor, and a diode to ground. This input signal should not be allowed to exceed 15V.

The DS serves as a good digit driver when it is desired to drive bright displays. The user must use caution in this mode however, to prevent overheating of the device by using too high a supply voltage or by operating at high ambient tempera- tures.

AC Parameters are guaranteed by DC correlated testing. The multiplexing circuit has its own. Thus, this is a.

74d925 using this driver with a 5V supply at room temperature, the display can be driven without segment resistors to full illu- mination. Features s Wide supply voltage range: A LOW signal on the Latch Enable input will latch the number in the counters into the internal output latches. The counters advance on negative edge of clock.

This input signal should not be allowed.

The user must use caution in this mode however. The input protection circuitry consists of a series resistor. The datahseet advance on negative edge of clock. Thus input signals exceeding V CC.
