General
The 74HC240D and 74HC244D are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS
technology.
They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
The 74HC240D is an inverting 3-state buffer and the 74HC244D are non-inverting 3-state buffers having two
active-low output enables.
These devices are designed to be used with 3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

(1) High speed: tpd = 10 ns (typ.) at VCC = 6.0 V
(2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25
(3) Balanced propagation delays: tPLH ≈ tPHL
(4) Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
