INTEGRATED CIRCUITS DATA SHEET 74LVC2245A Octal transceiver with direction pin, 30 Ω series termination resistors; 5 V tolerant input/output; 3-state Product specification Supersedes data of 2002 Jun 10 2003 Nov 17 Philips Semiconductors Product specification Octal transceiver with direction pin, 30 Ω series termination resistors; 5 V tolerant input/output; 3-state 74LVC2245A FEATURES DESCRIPTION • 5 V tolerant inputs/outputs for interfacing with 5 V logic The 74LVC2245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. • Wide supply voltage range from 1.2 to 3.6 V • CMOS low power consumption 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. • Direct interface with TTL levels • Inputs accept voltages up to 5.5 V • Integrated 30 Ω termination resistors • Complies with JEDEC standard no. 8-1A The 74LVC2245A is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. • ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. The 74LVC2245A features 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. • Specified from −40 to +85 °C and −40 to +125 °C. The 74LVC2245A is designed with 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 2.5 ns. SYMBOL PARAMETER tPHL/tPLH propagation delay An to Bn, Bn to An CI input capacitance CPD power dissipation capacitance per buffer CONDITIONS CL = 50 pF; VCC = 3.3 V VCC = 3.3 V; notes 1 and 2 Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; Σ(CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC. 2003 Nov 17 2 TYPICAL UNIT 3.6 ns 4.0 pF 13 pF Philips Semiconductors Product specification Octal transceiver with direction pin, 30 Ω series termination resistors; 5 V tolerant input/output; 3-state 74LVC2245A ORDERING INFORMATION PACKAGE TYPE NUMBER TEMPERATURE RANGE PINS PACKAGE MATERIAL CODE 74LVC2245AD −40 to +125 °C 20 SO20 plastic SOT163-1 74LVC2245ADB −40 to +125 °C 20 SSOP20 plastic SOT339-1 74LVC2245APW −40 to +125 °C 20 TSSOP20 plastic SOT360-1 74LVC2245ABQ −40 to +125 °C 20 DHVQFN20 plastic SOT764-1 FUNCTION TABLE See note 1.
