GENERAL DESCRIPTION
The MT5C1001 employs low power, high-performance silicon-gate CMOS technology. Static design eliminates the need for external clocks or timing strobes while CMOS circuitry reduces power consumption and provides for greater reliability. For flexibility in high-speed memory applications, ASI offers chip enable (CE\) and output enable (OE\) capability. These enhancements can place the outputs in High-Z for additional flexibility in system design. Writing to these devices is accomplished when write enable (WE|) and CE\ inputs are both LOW. Reading is accomplished when WE\ remains HIGH while CE\ and OE\ go LOW. The devices offer a reduced power standby mode when disabled. This allows system designs to achieve low standby power requirements. The "L" version provides an approximate 50 percent reduction in CMOS standby current (ISBC2) over the standard version. All devices operation from a single +5V power supply and all inputs and outputs are fully TTL compatible.

* Operating Temperature Ranges Industrial (-40oC to +85oC) IT Military (-55oC to +125oC) XT * 2V data retention/low power L
*Electrical characteristics identical to those provided for the 45ns access devices.

NOTES
1. 2. 3. All voltages referenced to VSS (GND). -3V for pulse width < 20ns ICC is dependent on output loading and cycle rates. The specified value applies with the outputs unloaded, and f = 1 Hz. t RC (MIN) This parameter is guaranteed but not tested. Test conditions as specified with the output loading as shown in Fig. 1 unless otherwise noted. tLZCE, tLZWE, tLZOE, t HZCE, tHZOE and tHZWE are specified with CL = 5pF as in Fig. 2. Transition is measured 200mV typical from steady state voltage,

allowing for actual tester RC time constant. At any given temperature and voltage condition, tHZCE is less than tLZCE, and tHZWE is less than tLZWE and tHZOE is less than tLZOE. 8. WE\ is HIGH for READ cycle. 9. Device is continuously selected. Chip enables and output enables are held in their active state. 10. Address valid prior to, or coincident with, latest occurring chip enable. 11. tRC = Read Cycle Time. 12. Chip enable (CE\) and write enable (WE\) can initiate and terminate a WRITE cycle. 7.
