GENUINE NATIONAL SEMICONDUCTOR
‘New old stock’
These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co.
They are date coded 9142 and have been stored correctly in their original tubes.
8-Bit, µP-Compatible, Analog-to-Digital Converters.
General Description
CMOS 8-bit successive approximation A/D
converters that use a differential potentiometric
ladder — similar to the 256R products. These converters are
designed to allow operation with the NSC800 and INS8080A
derivative control bus with TRI-STATE® output latches directly driving the data bus. These A/Ds appear like memory
locations or I/O ports to the microprocessor and no interfacing logic is needed.
Differential analog voltage inputs allow increasing the
common-mode rejection and offsetting the analog zero input
voltage value. In addition, the voltage reference input can be
adjusted to allow encoding any smaller analog voltage span
to the full 8 bits of resolution.
Features
Compatible with 8080 µP derivatives — no interfacing
logic needed – access time – 135 ns
Easy interface to all microprocessors, or operates “stand
alone”
Differential analog voltage inputs
Logic inputs and outputs meet both MOS and TTL
voltage level specifications
Works with 2.5V (LM336) voltage reference
On-chip clock generator
0V to 5V analog input voltage range with single 5V
supply
No zero adjust required
0.3″ standard width 20-pin DIP package
20-pin molded chip carrier or small outline package
Operates ratiometrically or with 5 VDC, 2.5 VDC, or
analog span adjusted voltage reference

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition, stored with us still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, 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.
