Genuine Philips HEF 4021BT in SO16 package
Select 2, 5 or 10 Pieces
synchronous serial data input (DS), a clock input (CP), an asynchronous active HIGH
parallel load input (PL), eight asynchronous parallel data inputs (D0 to D7) and buffered
parallel outputs from the last three stages (Q5 to Q7).
Each register stage is a D-type master-slave flip-flop with a set direct (SD) and clear direct
(CD) input. Information on D0 to D7 is asynchronously loaded into the register while PL is
HIGH, independent of CP and DS. When PL is LOW, data on DS is shifted into the first
register position and all the data in the register is shifted one position to the right on the
LOW-to-HIGH transition of CP. Schmitt trigger action makes the clock input highly tolerant
of slower rise and fall times.
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

Reel dated 0022 so have been in storage for some time we have therefore classified them as ‘new other’
They are however in pristine condition and we guarantee they will function perfectly.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, we have therefore classified them as new other, they are however unused and in good serviceable condition – the photographs are of one of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
