The TC74HC7240A/7244A are high speed CMOS OCTAL BUS
BUFFERs with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC7240A/7244A have same pin configuration and
function as the TC74HC240A/244A. And they have a hystereis
characterictics with each input, so TC74HC7240A/7244A can be
used as a line receiver, etc.
They have two active low output enables.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: tpd = 15 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
High noise immunity: VH = 1.1 V (typ.) at VCC = 5 V
Output drive capability: 15 LSTTL loads
Symmetrical output impedance: |IOH| = IOL = 6 mA (min)
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 6 V
Pin and function compatible with 74LS240/244
