Latches datasheet and documents for HEF4044BT,653
Latches Overview
The HEF4044BT,653 is a quad R/S latch with 3-state outputs manufactured by NXP Semiconductors. It features four independent latches, each equipped with an active LOW set input (1S to 4S), an active LOW reset input (1R to 4R), and an active HIGH 3-state output (1Q to 4Q). The device includes a common output enable input (OE) that controls the high impedance OFF-state of all outputs simultaneously. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS. The component complies with JEDEC standard JESD 13-B and supports fully static operation.
Latches Feature Summary
- Fully static operation for reliable data retention
- Common output enable input allows simultaneous control of all latch outputs
- High impedance OFF-state feature enables common bussing of outputs
- Complies with JEDEC standard JESD 13-B
Latches Applications
- Four-bit storage with output enable
Latches Procurement Notes
Verify the specific package variant against project requirements, as the HEF4044B family includes both DIP16 and SO16 options. Confirm that the ordering suffix matches the desired physical footprint before finalizing procurement. Ensure design compatibility with the specified operating temperature range and voltage levels.
Latches Selection Notes
Select this component when a quad latch with tri-state output capability is required. It is suitable for applications needing common bussing of multiple latch outputs via a single enable signal. Verify that the logic levels and supply voltage range align with the system architecture.
Latches Part Context
The HEF4044BT,653 belongs to the HEF4000 series of CMOS logic devices produced by NXP Semiconductors. This series is characterized by standardized symmetrical output characteristics and robust ESD protection capabilities. The part is designed for industrial temperature ranges and offers versatile integration into digital logic circuits requiring memory or state-holding functions.
