GENUINE Philips parts in SOP16 package
If you require GENUINE Philips parts look no further
See the photographs, the Philips logo is clearly visible and the chips photographed are from the same batch as the ones you will receive.
The HEF4043BT is a quad R/S latch with 3-state outputs with a common output enable input (OE).
Each latch has an active HIGH set input (1S to 4S), an active HIGH 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 (see 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.

Manufactured in the 90’s by Philips
These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. They are stored with us still sealed in original packaging (unopened boxes and tubes) and are in pristine condition. However having been in storage for some years (date code 9336) we have classified them as ‘new other’.
As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
