74LVC16245A; 74LVCH16245A

General description

The 74LVC(H)16245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 Volt. These features allow the use of these devices as a mixed 3.3 and 5 V environment.

The 74LVC(H)16245A is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver.

The 74LVCH16245A bushold data inputs eliminates the need for external pull-up resistors to hold unused inputs.

Features

• 5 V tolerant inputs/outputs for interfacing with 5 V logic
• Wide supply voltage range from 1.2 to 3.6 V
• CMOS low power consumption
• MULTIBYTE^TM flow-through standard pin-out architecture
• Low inductance multiple power and ground pins for minimum noise and ground bounce
• Direct interface with TTL levels
• High-impedance when V_CC =0 V
• All data inputs have bushold (74LVCH16245A only)
• Complies with JEDEC standard no. 8-1A
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
