FEATURES
VCC Current — Operating: 35mA — CMOS Standby: 100µA Access Times —55/70 ns Single 5 Volts ±10% Power Supply Easy Memory Expansion Using CE and OE Inputs Common Data I/O Three-State Outputs Fully TTL Compatible Inputs and Outputs Advanced CMOS Technology Automatic Power Down Packages —32-Pin 400 or 600 mil Ceramic DIP —32-Pin Ceramic SOJDESCRIPTION
Inputs are fully TTL-compatible. Access times of 55 ns and 70 ns are availale. CMOS is utilized to reduce power consumption to a low level. The P4C1023L device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A16. Reading is accomplished by device selection (CE low) and output enabling (OE) while write enable (WE) remains HIGH. By presenting the address under these conditions, the data in the addressed memory location is presented on the data input/output pins. The input/output pins stay in the HIGH Z state when either CE is HIGH or WE is LOW. The P4C1023L is packaged in a 32-pin 400 or 600 mil ceramic DIP and in a 32-pin ceramic SOJ.
