The TC74ACT240 and 244 are advanced high speed CMOS
OCTAL BUS BUFFERs fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The 74ACT240 is an inverting 3-state buffer while the
74ACT244 is non-inverting. Both devices have two active-low
output enables.
These devices are designed to be used in such applications as
3-state memory address drivers.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: tpd = 5.0 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 μA (max) at Ta = 25°C
• Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Pin and function compatible with 74F240/244
