74AVCH2T45 Dual-bit, dual-supply voltage level translator/transceiver 3-state Rev. 7 20 February 2018 Product data sheet 1 General description The 74AVCH2T45 is a dual bit, dual supply transceiver that enables bidirectional level translation. It features two data input-output ports (nA and nB), a direction control input (DIR) and dual supply pins (V and V ). Both V and V can be supplied at CC(A) CC(B) CC(A) CC(B) any voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins nA and DIR are referenced to V and pins nB are referenced to V . A HIGH on DIR CC(A) CC(B) allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA. The device is fully specified for partial power-down applications using I . The I OFF OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at CC(A) CC(B) GND level, both A and B are in the high-impedance OFF-state. The 74AVCH2T45 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: V : 0.8 V to 3.6 V CC(A) V : 0.8 V to 3.6 V CC(B) High noise immunity Complies with JEDEC standards: JESD8-12 (0.8 V to 1.3 V) JESD8-11 (0.9 V to 1.65 V) JESD8-7 (1.2 V to 1.95 V) JESD8-5 (1.8 V to 2.7 V) JESD8-B (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F Class 3B exceeds 8000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101C exceeds 1000 V Maximum data rates: 500 Mbps (1.8 V to 3.3 V translation) 320 Mbps (< 1.8 V to 3.3 V translation) 320 Mbps (translate to 2.5 V or 1.8 V) 280 Mbps (translate to 1.5 V) 240 Mbps (translate to 1.2 V) Suspend mode Bus hold on data inputsNexperia 74AVCH2T45 Dual-bit, dual-supply voltage level translator/transceiver 3-state Latch-up performance exceeds 100 mA per JESD 78 Class II Inputs accept voltages up to 3.6 V Low noise overshoot and undershoot < 10 % of V CC I circuitry provides partial Power-down mode operation OFF Multiple package options Specified from -40 C to +85 C and -40 C to +125 C 3 Ordering information Table 1.Ordering information Type number Package Temperature range Name Description Version 74AVCH2T45DC -40 C to +125 C VSSOP8 plastic very thin shrink small outline package 8 leads SOT765-1 body width 2.3 mm 74AVCH2T45GT -40 C to +125 C XSON8 plastic extremely thin small outline package no leads SOT833-1 8 terminals body 1 1.95 0.5 mm 74AVCH2T45GF -40 C to +125 C XSON8 extremely thin small outline package no leads SOT1089 8 terminals body 1.35 1 0.5 mm 74AVCH2T45GN -40 C to +125 C XSON8 extremely thin small outline package no leads SOT1116 8 terminals body 1.2 1.0 0.35 mm 74AVCH2T45GS -40 C to +125 C XSON8 extremely thin small outline package no leads SOT1203 8 terminals body 1.35 1.0 0.35 mm 4 Marking Table 2.Marking 1 Type number Marking code 74AVCH2T45DC K45 74AVCH2T45GT K45 74AVCH2T45GF K5 74AVCH2T45GN K5 74AVCH2T45GS K5 1 The pin 1 indicator is located on the lower left corner of the device, below the marking code. 74AVCH2T45 All information provided in this document is subject to legal disclaimers.
