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 VCC and 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
