• Operating voltage: 2.0V~5.5V
• Maximum input serial clock: 500kHz at VDD=2V, 2MHz at VDD=5V
• Operating current:
– less than 0.5μA at 2V
– less than 0.7μA at 3V
– less than 1.0μA at 5V
• TTL compatible
– VIH: 2.0V~VDD+0.3V at VDD=5V
– VIL: 0.3V~+0.8V at VDD=5V
• Two data transmission modes: single-byte, or burst mode
