6. Applies to the shift register in the slave mode. For details, refer to AC characteristics.
7. Connect oscillation resistor (Rf) and oscillation capacitance (Cf) as shown in this figure.
Oscillation frequency (f
OSC
) is twice as much as the frequency (f) at 1 or 2.

8. No lines are connected to output terminals and current flowing through the input circuit is
excluded. This value is specified at VIH = V
CC
and VIL = GND.
9. This value is specified for current flowing through GND in the following conditions: Internal
oscillation circuit is used. Each terminal of DS1, DS2, FS, SHL, M/S,
STB
, and FCS is connected
to V
CC
and each of CL1 and TH to GND. Oscillator is set as/ described in note 7.
10.This value is specified for current flowing through GND under the following conditions: Each
terminals of DS1, DS2, FS, SHL,
STB
, FCS and CR is connected to V
, CL1, TH, and M/S to
GND and the terminals CL2, M, and DL are respectively connected to terminals CL2, M, and DL
of the HD61203U under the condition described in note 9.
11.This value is specified for current flowing through V
EE
under the condition described in note 9.
Don’t connect any lines to terminal V.
12.This figure shows a typical relation among oscillation frequency, Rf and Cf. Oscillation frequency
may vary with the mounting conditions.
