74LVC245A, 74LVCH245A
General description
The 74LVC245A/74LVCH245A 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 V. These features allow the use of these devices as translators in a mixed 3.3 and 5 V environment.
The 74LVC245A/74LVCH245A is an octal transceiver with non-inverting 3-state bus compatible outputs in both send and receive directions.
The 74LVC245A/74LVCH245A has an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated.
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
- Direct interface with TTL levels
- Inputs accept voltages up to 5.5 V
- High-impedance when VCC =0 V
- bus-hold on all data inputs (74LVCH245A only)
- Complies with JEDEC standard no. 8-1A
- ESD protection:
- Specified from -40 to +85 Cel and -40 to +125 Cel.
-
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V
