OKI SEMICONDUCTOR
ELECTRICAL CHARACTERISTICS
[1] Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to the
conditions as detailed in the other sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
[1] trA, tfA – TTL interface, normal input buffer.
[2] trB, tfB – CMOS interface, normal input buffer.
[3] trC, tfC – TTL interface, Schmitt Trigger input buffer.
[4] trD, tfD – CMOS interface, Schmitt Trigger input buffer.
[1] 50-MHz oscillator frequency for VDD is 4.5 ~ 5.5 V.
