What is the different between input threshold shown in table 1 (p.25) and VIH and VIL shown in section 7.3 (p.9) in ISO724x d/s?

The input thresholds given in Table 1 on page 25 are the actual thresholds of device for both TTL and CMOS devices while VIL and VIH are the recommended LOW and HIGH input voltages that you should always apply. By following VIL and VIH levels, you are always making sure that device is reading input levels correctly.
The actual input thresholds implemented in device will be between VIL and VIH voltage levels to make sure there is sufficient margin given to recommended VIL and VIH levels. Customer should always apply input voltages according VIL and VIH recommendations. Thanks.
