FUNCTIONAL DESCRIPTION
Whenever a Logic "0" is applied to the Chip Select (
input,onebitofdataisclockedintotheshiftregisterfromthe
serial data input (DIN) with each negative transition of the
Clock (
) input.
is internally tied to VSS on some
versions. A Logic "1" present at the Load (LD) input will
cause a parallel transfer of data from the shift register to the
data latch. If the Load (LD) input is held high while data is
clocked into the shift register, the latch will be transparent.
All four logic inputs are TTL compatible on the HI-8010 and
CMOScompatibleontheHI-8110.
)
To display segments, a Logic "1" is stored in the appropriate
shift register bit position, and the segment output is out-of-
phasewiththebackplane.
The backplane output functions in 1 of 2 modes; externally
drivenorself-oscillating. WhentheLCDinputisexternally
driven with the LCDOPT input open circuit (Figure 2), the
backplane output will be in-phase with LCD. Utilizing the
self-oscillating mode, inputs LCD and LCDOPT are tied
together and connected to an RC circuit (Figure 3).
A 150K
resistor with a 470pF capacitor generates an
approximate backplane frequency of 100Hz. The
LCD/LCDOPT oscillator frequency is divided by 256 to
determine the backplane output frequency.
