74ALVCH162245

16-bit bus transceiver with direction pin and

30 Ω termination resistor; 3-state

Rev. 3 — 16 January 2018

Product data sheet

1 General description

The 74ALVCH162245 is a 16-bit transceiver featuring non-inverting 3-state bus

compatible outputs in both send and receive directions.

The 74ALVCH162245 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 74ALVCH162245 is designed with 30 Ω series resistors in both HIGH and LOW

output states.

The 74ALVCH162245 has active bus hold circuitry which is provided to hold unused or

floating data inputs at a valid logic level. This feature eliminates the need for external

pull-up or pull-down resistors.

2 Features and benefits

• Wide supply voltage range from 1.2 V to 3.6 V

• CMOS low power consumption

• MultiByte flow-through standard pin-out architecture

• Low inductance multiple V_CCand GND pins for minimum noise and ground bounce

• Direct interface with TTL levels (2.7 V to 3.6 V)

• Bus hold on all data inputs

• Integrated 30 Ω termination resistor

• Complies with JEDEC standards:

– JESD8-5 (2.3 V to 2.7 V)

– JESD8B/JESD36 (2.7 V to 3.6 V)

• ESD protection:

– HBM ANSI/ESDA/JEDEC JS-001 exceeds 2000 V

– CDM JESD22-C101E exceeds 1000 V
