This PDF document is about the product specification of 74F219A 64-bit TTL bipolar RAM, which features high speed performance and non-inverting (3-State) outputs.
This document is a product specification datasheet for the Philips 74F219A integrated circuit. It describes a high-speed, 64-bit TTL bipolar RAM organized as a 16-word by 4-bit array. The device features non-inverting outputs, Schottky clamp TTL technology, and 3-state outputs controlled by a chip enable input. It is designed to replace the 74F219 with improved performance, offering an address access time of 8ns maximum compared to 28ns for the previous model.
| Organization | 16-word by 4-bit array |
|---|---|
| Address access time | 8ns max |
| Power dissipation | 4.3mW/bit typ |
| Operating temperature | 0°C to +70°C |
| Package type | 16-pin plastic Dual In-line Package |
The maximum address access time is 8ns.
The outputs are in high impedance state whenever the chip enable (CE) is high.
