SN54S482, SN74S482 is a 4-bit slice expandable control element produced by Texas Instruments
The 'S482 is a high-performance Schottky TTL 4-bit-slice control element designed for use in any computer or control application requiring the coupling of high-performance bipolar speeds with the flexibility of microprogram control and bit-slice expandability. Comprised of an output register, push-pop stack, and a full adder, it provides the capability to implement multiway testing needed to generate or determine the source of the next function of microprogram address.
| Supply Voltage (Vcc) | 4.75 V to 5.25 V |
|---|---|
| Operating Temperature (SN54S482) | -55°C to 125°C |
| Operating Temperature (SN74S482) | 0°C to 70°C |
Two 'S482 elements can address up to 256 words of microprogram.
The 4-word push-pop stack can be used for nesting up to four levels of program or return (link) addresses.
