Product Summary

The 82HS321A/BJA is field programmable, which means that custom patterns are immediately available by following the Philips Semiconductors Generic II fusing procedure. The device is supplied with all outputs at a logic high. It includes on-chip decoding and 2 chip enable inputs for ease of memory expansion. It features 3-state outputs for optimization of word expansion in bused organizations.
