Each input level is equivalent to LS-TTL. Therefore, the devices can be driven directly by LS-TTLs. Channels 1 and 2 are turned on or off at the same time. 102 V ±0.3 Conditions Conditions Ripple Rejection mV VIN=5V, IO=0 to 1A VDIF1 ∆VO1/∆Ta Temperature Coefficient of mV VIN=4.5 to 10V, IO=10mA ∆VOLOAD1 Dropout Voltage V 20 Conditions Conditions Load Regulation 2.550 VIN=5V, IO=10mA ∆VOLINE1 Line Regulation Unit typ.
