HEF4044B
Datasheet
General description
The HEF4044B is a quad R/S latch with 3-state outputs, with a common output enable input (OE). Each latch has 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).
When OE is HIGH, the latch output (nQ) is determined by the nR and nS inputs as shown in Table 3. When OE is LOW, the latch outputs are in the high impedance OFF-state. OE does not affect the state of the latch. The high impedance off-state feature allows common bussing of the outputs.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the industrial (-40 Cel to +85 Cel) temperature range.
Features
- Fully static operation
- 5 V, 10 V, and 15 V parametric ratings
- Standardized symmetrical output characteristics
- Operates across the full industrial temperature range -40 Cel to +85 Cel
- Complies with JEDEC standard JESD 13-B
- ESD protection:
- HBM JESD22-A114E exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
