UPD445L Datasheet (NEC) - FULLY DECODED 4096 STATIC CMOS RAM

UPD445L, FULLY DECODED 4096 STATIC CMOS RAM

The ~PD445L is a very low power 4,,096 bit (1024 words by 4 bits) static RAM fabricated with NEC's complementary MOS (CMOS) process, It has two chip enable inputs (CE1, I I ' CE2).

Minimum standby current is drawn when CE1 is at a high level, while inhibiting all address and control line transition
