74ALVT16373DGG,118

Overview

The Nexperia 74ALVT16373DGG,118 is a 16-bit transparent D-type latch with 3-state outputs, manufactured using BiCMOS technology. It operates within a supply voltage range of 2.3 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device supports two independent 8-bit latches or a single 16-bit configuration, utilizing separate latch enables (1LE, 2LE) and output enables (1OE, 2OE). It includes bus-hold data inputs to eliminate external pull-up resistors and IOFF circuitry for partial power-down mode operation. The component is housed in a TSSOP48 package (SOT362-1) and functions reliably across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• BiCMOS high-speed performance with strong output drive capability
• Bus-hold data inputs eliminate the need for external pull-up resistors
• IOFF circuitry provides partial power-down mode operation
• Power-up reset and power-up 3-state functionality

Applications

• Direct interface with TTL levels
• Input and output interface capability to systems at 5 V supply
• Live insertion/extraction permitted applications
