The high-speed, low-power latch is ideal for temporary storage of data. The device can be used for implementing memory address latches, I/O ports, and bus drivers. The Output Enable and Latch Enable controls are organized to operate each device as four 8-bit latches, two 16- bit latches, or one 32-bit latch. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin. The ALVCH32373 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The ALVCH32373 has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistor. 2 OE D C 2 LE 2 D1 2 Q1 H3 H4 E5 E2 4 OE D C 4 LE 4 D1 4 Q1 T3 T4 N5 N2 1 OE D C 1 LE D1 1 Q1 TO SEVEN OTHER CHANNELS 3 OE D C 3 LE 3 D1 3 Q1 J3 J4 J5 J2 A3 A4 A5 A2 TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS |
