- - Low-voltage operation: VCC = 2.0 to 3.6 V High-speed operation: tpd = 7.0 ns (max) (VCC = 3.0 to 3.6 V) Output current: |IOH|/IOL = 24 m A (min) (VCC = 3.0 V) Latch-up performance: ±500 m A Available in SSOP Bidirectional interface between 5.0 V and 3.3 V signals Power-down protection provided on all inputs
..
Pin and function patible with the 74 series (74AC/HC/F/ALS/LS etc.) 646 type
Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down resistors.
