MC14044BCP

Latches Overview

The MC14044BCP is a CMOS MSI Quad R-S Latch manufactured by onsemi. It features four independent latches with Set and Reset inputs, providing an independent Q output for each. The outputs are gated through three-state buffers controlled by a common enable input; a logical high enables the outputs while a low disconnects them into a high-impedance state. Constructed using MOS P-Channel and N-Channel enhancement mode devices, it operates within a supply voltage range of 3.0 Vdc to 18 Vdc. The device includes double diode input protection and can drive two Low-power TTL loads or one Low-Power Schottky TTL load.

Latches Feature Summary

• Quad R-S latch configuration with independent Set and Reset inputs
• Three-state outputs managed by a single common enable signal
• Double diode input protection against static voltages
• Capable of driving standard TTL loads across rated temperature ranges

Latches Applications

• Data storage circuits requiring multiple independent memory bits
• Interface logic for systems utilizing TTL-compatible signaling
• Control logic where output tri-stating is required for bus sharing

Latches Procurement Notes

Verify that the specific suffix 'CP' corresponds to the requested package type, as the official datasheet primarily lists SOIC-16 variants (DG, D, DR2G). Confirm RoHS compliance status and check for NLV prefix requirements if automotive qualification is needed. Ensure ordering information matches the exact pinout and shipping format specified in the manufacturer's current documentation.

Latches Selection Notes

Select this component when a quad latch with tri-state capability is required. It is suitable for designs needing to interface with TTL logic families due to its drive capabilities. Consider the wide operating voltage range and temperature stability. Verify that the package availability aligns with manufacturing constraints, noting that alternative suffixes may offer different packaging options.

Latches Part Context

This part belongs to the MC14043B/MC14044B series of CMOS MSI logic devices. These components are designed for general-purpose digital applications requiring reliable data retention and bus isolation. The series is built on monolithic CMOS technology, offering low power consumption and high noise immunity compared to earlier logic families.

Latches Replacement Considerations

MC14043BDG: Same functional logic but in SOIC-16 surface mount package instead of DIP.
