Frequently Asked Questions
What is the operating voltage range of the SN74BCT240N?
The SN74BCT240N operates over a supply voltage range of 4.5V to 5.5V, making it compatible with standard 5V TTL and CMOS logic systems. This range ensures stable operation across typical industrial and commercial temperature environments.
What is the output drive current capability of the SN74BCT240N?
The SN74BCT240N provides a maximum output low current (IOL) of 64mA, thanks to its BiCMOS output stage. This high sink current capability allows it to drive heavily loaded buses with a load capacitance up to 50pF per output, minimizing signal degradation.
What are typical applications for the SN74BCT240N?
The SN74BCT240N is commonly used as a bus driver in microprocessor systems, memory address and data buses, and industrial control boards. Its 3-state outputs and high drive current make it suitable for any application requiring signal buffering and isolation on shared bus architectures.
Can the SN74BCT240N replace other 74240-series bus drivers?
Yes, the SN74BCT240N is pin-compatible with other 74240-series octal inverting bus drivers such as the 74LS240 and 74HCT240. However, the BCT variant offers superior drive strength and faster switching due to its BiCMOS technology, which should be verified against your system timing and power requirements.
What package type is the SN74BCT240N available in?
The SN74BCT240N is available in a 20-pin dual-in-line (DIP) through-hole package (PDIP-20), making it easy to use in prototyping, legacy board designs, and applications where through-hole mounting is preferred.
