Overview
The 74HC123AP-E is a dual retriggerable monostable multivibrator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.0 V to 6.0 V and features propagation delays of 210 ns, 42 ns, and 36 ns. The device provides a maximum power supply current of 4 µA and supports low-level output currents of 5.2 mA and high-level output currents of -5.2 mA. Designed for through-hole mounting, it utilizes a PDIP-16 package and functions reliably across an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Dual retriggerable monostable multivibrator architecture
- Schmitt trigger inputs on nA and nB terminals for noise tolerance
- Direct reset capability to terminate output pulses immediately
Applications
- Timing pulse generation circuits
- Frequency division applications
- Pulse width modulation systems
Procurement Notes
Verify the specific manufacturer designation, as the model prefix indicates Toshiba origin while the brand specifies Renesas. Confirm RoHS compliance status directly with the supplier documentation. Ensure the PDIP-16 through-hole package matches the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel timing solution is required with Schmitt trigger input capabilities. The HC logic family ensures compatibility with standard CMOS interfaces. Verify that the 2.0 V to 6.0 V operating voltage range aligns with the system power supply constraints.
Part Context
This component belongs to the 74HC123 series of monostable multivibrators. It serves as a digital timing element capable of generating precise output pulses in response to external triggers. The device is part of a broader family of logic ICs designed for general-purpose timing and waveform shaping tasks in electronic systems.
Replacement Considerations
Compatible substitutes include the 74HC123D and 74HC123N variants. These alternatives offer similar functional characteristics but may differ in physical packaging dimensions such as SO16 or DIP16 configurations.
