NXP Semiconductors 74LVC322245A
The 74LVC(H)322245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. These features allow the use of these devices in a mixed 3.3 and 5 V environment. The 74LVC(H)322245A is a 32-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions.FEATURES
● 5 V tolerant inputs/outputs for interfacing with 5 V logic● Wide supply voltage range of 1.2 to 3.6 V
● Complies with JEDEC standard no. 8-1A
● CMOS low power consumption
● MULTIBYTE™ flow-trough standard pin-out architecture
● Low inductance multiple power and ground pins for minimum noise and ground bounce
● Direct interface with TTL levels
● Bus hold on data inputs (74LVCH322245A only)
● Integrated 30 Ω termination resistors
● Typical output ground bounce voltage: VOLP <0.8 V at VCC = 3.3 V; Tamb = 25 °C
● Typical output VOH undershoot voltage: VOHV >2 V at VCC = 3.3 V; Tamb = 25 °C
● Power-off disabled outputs, permitting live insertion
● Plastic fine-pitch ball grid array package.
DESCRIPTION
74LVC322245A; 74LVCH322245A Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. The 74LVC(H)322245A features two output enable (nOE) inputs for easy cascading and two send or receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated.
