6 / 16 page ASM5P23S09A August 2003 ASM5P23S05A rev 2.0 3.3V ‘SpreadTrak’ Zero Delay Buffer 6 of 16 Notice: The information in this document is subject to change without notice. Electrical Characteristics for ASM5P23S05A and ASM5P23S09A - Commercial Temperature Devices Parameter Description Test Conditions Min Max Unit VIL Input LOW Voltage 5 0.8 V VIH Input HIGH Voltage 5 2.0 V IIL Input LOW Current VIN = 0V 50.0 µA IIH Input HIGH Current VIN = VDD 100.0 µA VOL Output LOW Voltage 6 IOL = 8mA (-1) IOH = 12mA (-1H) 0.4 V VOH Output HIGH Voltage 6 IOL = -8mA (-1) IOH = -12mA (-1H) 2.4 V IDD Supply Current Unloaded outputs at 66.67 MHz, SEL inputs at VDD TBD mA Notes: 5. REF input has a threshold voltage of VDD/2 6. Parameter is guaranteed by design and characterization. Not 100% tested in production 7. S1 / S2 inputs are CMOS, TTL compatible inputs – The input must toggle somewhere between 0.8 and 2.0. We guarantee the limits of 0.8 and 2.0, but can't guarantee anything tighter than that. As Vdd moves higher the toggle point will move higher, but will always stay below 2.0V. As Vdd moves lower, the toggle point will move lower, but always stay higher than 0.8V. What the 2.0V MIN Vih specification means is that you put 2.0V or a higher voltage into the device, and you will have a logic HIGH. If you put 0.8V or a lower voltage into the device, you will have a logic LOW ( Vil spec = 0.8V max). It will toggle someplace in between 0.8V and 2.0V, but we don't guarantee exactly where, and the exact point will change depending upon conditions. Characterization shows we toggle at 1.1V and 1.5V (showing a little hysteresis), everything is perfect. We meet spec, plus have ~ 300mV noise immunity on the low end and ~500mV noise immunity on the high side. Under nominal conditions, with no hysteresis, most devices will toggle at about 1.5V for both high and low.
