TC74ACT245F
Features
(Note 1) (Note 2)
- High speed: tpd = 4.7 ns (typ.) at VCC = 5 V
- Low power dissipation: ICC = 8 μA (max) at Ta = 25°C
- patible with TTL outputs
: VIL = 0.8 V (max), VIH = 2.0 V (min)
- Symmetrical output impedance
: |IOH| = IOL = 24 m A (min) Capability of driving 50 Ω transmission lines.
- Balanced propagation delays: tp LH ∼- tp HL
- Pin and function patible with 74F245/640
Weight DIP20-P-300-2.54A SOP20-P-300-1.27A TSSOP20-P-0044-0.65A
: 1.30 g (typ.) : 0.22 g (typ.) : 0.08 g (typ.)
Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down resistors.
