Minimum address setup and hold time requirements must be met. After the required hold time the addresses may change state without affecting device operation. In order for the output to be read S1, S2 and E be low, W must be high. When E goes high the output data is latched into an on chip register. Taking either or both S1 or S2 high, forces the output buffer to a high impedance state.

Device selected only if both S1 and S2 are low, and deselected if either S1 or S2 are high. By positioning the W pulse at different times within the E low time (TELEH), various types of write cycles may be performed. If the E low time (TELEH) is greater than the W pulse (TWLWH), plus an output enable time (TSLQX), a combination read write cycle is executed. Data may be modified an indefinite number of times during any write cycle (TELEH). The write cycle is initiated by the falling edge of E which latches the address information into the on chip registers. The write portion of the cycle is defined as E, W, S1 and S2 being low simultaneously. W may go low anytime during the cycle provided that the write enable pulse setup time (TWLEH) is met. The write portion of the cycle is terminated by the first rising edge of either E, W, S1 or S2. Data setup and hold times must be referenced to the terminating signal. The data input and data output pins may be tied together for use with a common I/O data bus structure. When using the RAM in this method allow a minimum of one output disable time (TWLQZ) after W goes low before applying input data to the bus. This will ensure that the output buffers are not active. If a series of consecutive write cycles are to be performed, the W line may remain low until all desired locations have been written. When this method is used, data setup and hold times must be referenced to the rising edge of E. Test Load Circuit DUT (NOTE 1) CL IOH + - 1.5V EQUIVALENT CIRCUIT NOTE: 1.
