The SN74172 is a monolithic chip containing the equivalent of 20 gates on a single die. It functions as a 16-bit register file organized into eight words of two bits each. The device features multiple address decoding circuitry that allows for simultaneous reading and writing operations on different word locations.
| Organization | Eight words of two bits each |
|---|---|
| Propagation delay (read select, low-to-high) | 33 ns typical |
| Propagation delay (clock, low-to-high) | 35 ns typical |
Yes, independent address decoding permits simultaneous reading and writing on two word locations.
The register file is organized as eight two-bit word locations.
Up to 129 compatible outputs can be connected to a common system bus.
