Frequently Asked Questions
What is the propagation delay of the SN74LS123N-P2?
The SN74LS123N-P2 has a propagation delay of 28 ns, which is characteristic of the low-power Schottky TTL (LS-series) logic family. This fast response time makes it suitable for timing-sensitive pulse generation and one-shot applications in digital circuits.
How many monostable multivibrator channels does the SN74LS123N-P2 contain?
The SN74LS123N-P2 contains two independent retriggerable monostable multivibrator channels. Each channel has its own timing resistor and capacitor inputs, allowing independent pulse width programming. This dual-channel design makes it a highly versatile timing component for compact logic designs.
What package and pin count does the SN74LS123N-P2 use?
The SN74LS123N-P2 uses a 16-pin plastic dual-in-line (PDIP) through-hole package. This through-hole format is ideal for prototyping on breadboards and fits standard 0.6-inch DIP sockets, making it easy to use in both new designs and direct replacements for existing 74LS123 circuits.
Can the SN74LS123N-P2 be used as a replacement for the SN74LS122?
The SN74LS123N-P2 (dual channel) and SN74LS122 (single channel) are related but not pin-compatible. The SN74LS123 provides two independent monostable channels versus the single channel of the SN74LS122. Always verify pinout and timing component connections before substituting these devices in an existing design.
