Application Circuits from the Datasheet

The A68064 excels in three common scenarios: a68064 datasheet

1. Shift in data: Data In (pin 2) is clocked on the rising edge of CLK (pin 3) – MSB first.
2. Latch data: When STROBE (pin 4) is high, data from the shift register transfers to the output latches.
3. Enable outputs: Drive OE (pin 5) low. Outputs become active according to the latched data.
4. Cascade: Data Out (pin 20) provides the last bit of the shift register after the 8th clock cycle, allowing connection to the Data In of a second A68064.

PD = ∑ (VCE(sat) × IOUT(n)) + (VDD × IDD) Output saturation voltage (VCE(sat)) : 0

Example timing sequence (from datasheet):

• Set Data In = 1 (turn on output 1)
• Apply positive CLK pulse
• Repeat for desired bits
• Set STROBE high for at least 200 ns
• Set OE low to enable outputs
