1 See Figure 2. Temperature range for Y version is −40°C to +125°C. Guaranteed by design and characterization, not subject to production test.
2 All input signals are specified with tr = tf = 5ns (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH)/2. Digital output timing measured
with load circuit in Figure 3.
