Description
Octal Buffers AND LINE Drivers WITH 3-state Outputs
All product names, trademarks, brands and logos used on this site are the property of their respective owners. The depiction, description or sale of products featuring these names, trademarks, brands and logos is for identification purposes only and is not intended to indicate any affiliation with or authorization by any rights holder.
General Description
These buffers/line drivers are designed to improve both the performance and PC board density of 3-STATE buffers/ drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers. Featuring 400 mV of hysteresis at each low current PNP data line input, they provide improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133Ω.
Features
● 3-STATE outputs drive bus lines directly
● PNP inputs reduce DC loading on bus lines
● Hysteresis at data inputs improves noise margins
● Typical IOL(sink current) 24 mA
● Typical IOH(source current) -15 mA
● Typical propagation delay times
- Inverting 10.5 ns
- Noninverting 12 ns
● Typical enable/disable time 18 ns
● Typical power dissipation (enabled)
- Inverting 130 mW
- Noninverting 135 mW

The testing result for the Intergrated Circuits 74LS240N ordered from Utsource website was satisfactory. All the pins were tested and the results showed that the circuit was working properly. The output voltage was within the specified range and the power consumption was also in line with the expected values. The circuit was able to handle the expected load and no issues were observed during testi
