Conditions
VCC = 5.5, VIN = GND to VCC
SCS# = VIH, OE# = VIH, VOUT = GND to VCC
SCS# = VIL, OE# = ECS# = VIH, f = 5MHz, VCC = 5.5
ECS# = SCS# = VIH, OE# = VIH, f = 5MHz, VCC = 5.5
IOL = 8.0mA, VCC = 4.5
IOL = 2.1mA, VCC = 4.5
IOH = -4.0mA, VCC = 4.5
IOH = -1mA, VCC = 4.5
ECS# = VIL, OE# = SCS# = VIH
IOL = 2.1 mA, VCC = 4.5V
IOH = 400 µA, VCC = 4.5V
NOTES:
1. The ICC current listed includes both the DC operating current and the frequency dependent component (@ 5 MHz).
The frequency component typically is less than 2 mA/MHz, with OE at VIH.
2. DC test conditions: VIL = 0.3V, VIH = VCC - 0.3V
