Frequently Asked Questions
How much output sink current can the SN74BCT623NSRG4 handle for bus driving applications?
The SN74BCT623NSRG4 provides a maximum output sink current (I(ol)) of 64 mA per output, enabling it to drive heavy bus loads including multiple receivers or long PCB traces. This high drive strength is characteristic of the BCT/FBT logic family for reliable signal integrity at standard TTL logic levels.
For a backplane design with 50 pF trace capacitance, can the SN74BCT623NSRG4 maintain signal integrity?
Yes, the SN74BCT623NSRG4 is rated for a load capacitance (CL) of 50 pF per output, which corresponds to typical backplane and PCB trace capacitances. Combined with 64 mA sink drive current, it maintains fast output transitions and valid logic levels across 8 bidirectional channels at standard bus operating voltages.
When should SN74BCT623NSRG4 be preferred over standard 74HC245 octal bus transceivers?
SN74BCT623NSRG4 is preferred when higher output drive strength is needed; BCT devices source and sink up to 64 mA compared to approximately 8 mA for 74HC245 CMOS devices. This makes SN74BCT623NSRG4 suitable for TTL-level bus systems, industrial backplanes, or legacy microprocessor interfaces where strong bus drive at 5 V logic levels is required.
