GENERAL DESCRIPTION
The HEF4021B is an 8-bit static shift register (parallel-to-serial converter) with a
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

Features and benefits
 Tolerant of slower rise and fall times
 Fully static operation
 5 V, 10 V, and 15 V parametric ratings
 Standardized symmetrical output characteristics
 Specified from -40 +’C to +125 ‘C
 Complies with JEDEC standard JESD 13-B

SO16 Plastic small outline package; 16 leads; body width 3.9 mm

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.


These Philips parts are now obsolete for current NXP datasheet (exactly the same device)

 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 rather than the commercial equivalent.
