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 OCTALBUS 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. Packaging
