74HC240D,74HC244D CMOS Digital Integrated Circuits Silicon Monolithic 74HC240D,74HC244D 1. Functional Description • Octal Bus Buffer 74HC240D: INVERTED, 3-STATE OUTPUTS 74HC244D: NON-INVERTED, 3-STATE OUTPUTS 2. 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. 3. Features (1) Wide operating temperature range: Topr = -40 to 125 � (Note 1) (2) High speed: tpd = 10 ns (typ.) at VCC = 6.0 V (3) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25 � (4) Balanced propagation delays: tPLH ≈ tPHL (5) Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V Note1 1:Operating Range spec of Topr = -40 � to 125 � is applicable only for the products which manufactured after July 2020. 4.

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). Note 1: PD derates linearly with -8 mW/� above 85 � 10.
