FEATURES
● Operating voltage 2.7V~5.5V● Low power consumption – Operation: 25mA max. (VCC=5V) 10mA max. (VCC=3V) – Standby: 30µA max. (VCC=5V) 10µA max. (VCC=3V)
● Access time:150ns max. (VCC=5V) 250ns max. (VCC=3V)
GENERAL DESCRIPTION
This flexibility not only allows easy interface with most microproc-● 32768×8 bits of mask ROM
● Mask options: chip enable CE/CE/OE1/OE1 and output enable OE/OE/NC
● TTL compatible inputs and outputs
● Tristate outputs
● Fully static operation
● Package type: 28-pin DIP/SOP essors, but also eliminates bus contention in multiple bus microprocessor systems. An additional feature of the HT23C256 is its ability to enter the standby mode whenever the chip enable (CE/CE) is inactive, thus reducing current consumption to below 30µA. The combination of these functions makes the chip suitable for high density low power memory applications. Block Diagram 1 24th Aug ’98 Pin Assignment HT23C256 Pin
