SN74ALVCH162373GR

产品概述

The SN74ALVCH162373GR is a 16-bit Transparent D Latch with 3-state outputs. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers. This device can be used as two 8-bit latches or one 16-bit latch. When the LE input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. A buffered OE input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without need for interface or pull-up components. OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

• Member of the Texas Instruments Widebus™ family
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Output ports have equivalent 26R series resistors, so no external resistors are required
• Latch-up performance exceeds 250mA per JESD 17
• Green product and no Sb/Br
