Signetics 82S226
The 82S226 (Open Collector Outputs) and the 82S229 (Tri-State Outputs) are Bipolar 1024-Bit Read Only Memories, organized as 256 words by 4 bits per word. They are fully TTL compatible, and include on-chip decoding and two chip enable inputs for ease of memory expansion. They feature either Open Collector or Tri-State outputs for optimization of word expansion in bussed organizations.DESCRIPTION
PIN CONFIGURATION Both the 82S226 and 82S229 are also fully compatible with the 82S 126/ 129, Signetics' 1024-Bit Programmable Read Only Memories. Both 82S226 and 82S229 devices are available in the commercial and military temperature ranges. For the commercial temperature range (O°C to +75°C) specify N82S226/229, B or F. For the military temperature range (-55°C to +125°C) specify S82S226/229, F only. B, F PACKAGE* A6 1 A5 2 16 Vcc 14 CE2 13 CE1 12 01FEATURES
