SN74ALVCH16373 16-BIT TRANSPARENT D-TYPE LATCH WITH 3-STATE OUTPUTS www.ti.com FEATURES • • • • • • • Member of the Texas Instruments Widebus™ Family Operates From 1.65 V to 3.6 V Max tpd of 3.6 ns at 3.3 V ±24-mA Output Drive at 3.3 V Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors Latch-Up Performance Exceeds 250 mA Per JESD 17 ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) XXXX DESCRIPTION/ORDERING INFORMATION This 16-bit transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. The SN74ALVCH16373 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 latch-enable (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.

In the high-impedance state, the outputs neither load nor drive the buslines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without need for interface or pullup 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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
